.06Miltenyi Biotec B.V. & Co. KGpage 1/4Contents1. Description 1.1 Principle of the MACS® Separation 1.2 Background information 1.3 Applications1.4 Reagent and instrument requirements2. Protocol2.1 Sample preparation 2.2 Magnetic labeling 2.3 Magnetic separation2.4 C ell separation with the autoMACS® Pro Separator3. Example of a separation using CD45 (TIL) MicroBeadsWarningsReagents contain sodium azide. Under acidic conditions sodium azide yields hydrazoic acid, which is extremely toxic. Azide compounds should be diluted with running water before discarding. These precautions are recommended to avoid deposits in plumbing where explosive conditions may develop.1. DescriptionThis product is for research use ponents1 mL CD45 (TIL) MicroBeads, mouse:MicroBeads conjugated to monoclonal anti-mouse CD45 antibodies (isotype: rat IgG2b).CapacityFor 10⁹ total cells, up to 100 separations.Product format CD45 (TIL) MicroBeads are supplied in buffercontaining stabilizer and 0.05% sodium azide.StorageStore protected from light at 2−8 °C. Do not freeze. The expiration date is indicated on the vial label.1.1 Principle of the MACS® SeparationFirst, the CD45+cells are magnetically labeled with CD45 (TIL) MicroBeads. Then, the cell suspension is loaded onto a MACS® Column, which is placed in the magnetic field of a MACS Separator. The magnetically labeled CD45+ cells are retained within the column. The unlabeled cells run through; this cell fraction is thus depleted of CD45+ cells. After removing the column from the magnetic field, the magnetically retained CD45+ cells can be eluted as the positively selected cell fraction. To increase the purity, the positively selected cell fraction containing the CD45+ cells must be separated over a second column.1.2 Background informationCD45 (TIL) MicroBeads, mouse have been developed for theisolation of tumor-infiltrating leukocytes (TILs) from single-cell suspensions of solid mouse tumors. The CD45 antigen is expressed on all cells of hematopoietic origin except erythrocytes and platelets.1.3 Applications●Positive selection of CD45+ leukocytes from solid mouse tumors, e.g., B16F10, 4T1, or CT26.WT.1.4 Reagent and instrument requirements●Buffer: Prepare a solution containing phosphate-buffered saline (PBS), pH 7.2, 0.5% bovine serum albumin (BSA), and 2 mM EDTA by diluting MACS® BSA Stock Solution (# 130-091-376) 1:20 with autoMACS® Rinsing Solution (# 130-091-222). Keep buffer cold (2−8 °C). Degas buffer before use, as air bubbles could block the column. Always use freshly prepared buffer. ▲ Note: EDTA can be replaced by other supplements such as anticoagulant citrate dextrose formula-A (ACD-A) or citrate phosphate dextrose (CPD). BSA can be replaced by other proteins such as mouse serum albumin, mouse serum, or fetal bovine serum (FBS). Buffers or media containing Ca2+ or Mg2+ are not recommended for use.●MACS Columns and MACS Separators: CD45+ cells can be enriched by using MS or LS Columns. Positive selection can also be performed by using the autoMACS Pro or the MultiMACS™ Cell24 Separator.Positive selection MS 10⁷ 2 ×10⁷MiniMACS, OctoMACS, VarioMACS, SuperMACS II LS4 ×10⁷4 ×10⁷5 ×10⁷5 ×10⁷MidiMACS, QuadroMACS, VarioMACS, SuperMACS IIMultiMACS Cell24 Separator PlusautoMACS5 ×10⁷10⁸autoMACS ProMulti-24 Column Block (per column)2 ×10⁷2.5 ×10⁷MultiMACS Cell24 Separator Plus ▲Note: Column adapters are required to insert certain columns into the VarioMACS™ or SuperMACS™ II Separators.

Protocol2.1 Sample preparationFor preparation of a single-cell suspension from solid mouse tumors use the Tumor Dissociation Kit, mouse (# 130-096-730) in combination with the gentleMACS™ Dissociators.For details refer to /protocols.▲ Dead cells may bind non-specifically to MACS® MicroBeads. To remove dead cells, we recommend using the Dead Cell Removal Kit (# 130-090-101).2.2 Magnetic labeling▲ Cells can be labeled with MACS MicroBeads using the autolabeling function of the autoMACS® Pro Separator. For more information refer to section 2.4.▲ Work fast, keep cells cold, and use pre-cooled solutions. This will prevent capping of antibodies on the cell surface and non-specific cell labeling.▲ Volumes for magnetic labeling given below are for up to 10⁷ total cells. When working with fewer than 10⁷ cells, use the same volumes as indicated. When working with higher cell numbers, scale up all reagent volumes and total volumes accordingly (e.g. for 2×10⁷ total cells, use twice the volume of all indicated reagent volumes and total volumes).▲ For optimal performance it is important to obtain a single-cell suspension before magnetic labeling. Pass cells through 30 µm nylon mesh (MACS SmartStrainers (30 µm), # 130-098-458). Moisten filter with buffer before use.▲ The recommended incubation temperature is 2–8 °C. Higher temperatures and/or longer incubation times may lead to non-specific cell labeling. Working on ice may require increased incubation times.1. Determine cell number.2. Centrifuge cell suspension at 300×g for 5 minutes. Aspiratesupernatant completely.3. Resuspend cell pellet in 90 µL of buffer per 10⁷ total cells.▲ Note: Always use freshly prepared buffer.4.

(Optional) Add staining antibodies according tomanufacturer’s recommendations.7. Add buffer to a final volume of 500 μL for up to 5×10⁷ cells.▲Note: If more cells were used, split the sample onto multiple columns duringmagnetic separation.▲Note: For higher cell numbers, scale up buffer volume accordingly.8.Proceed to magnetic separation (2.3).2.3 Magnetic separation▲ Choose an appropriate MACS Column and MACS Separator according to the number of total cells and the number of CD45+ cells. For details refer to the table in section 1.4.▲ Note: MS Columns are recommended for highest purity of CD45+ cells. LSColumns are recommended for highest recovery of CD45+ cells.▲ For optimal performance it is important to obtain a single-cell suspension before magnetic separation. Pass cells through 30 µm nylon mesh (Pre-Separation Filters (30 µm), # 130-041-407) to remove cell clumps which may clog the column. Moisten filter with buffer before use.▲Always wait until the column reservoir is empty before proceeding to the next step.Magnetic separation with MS or LS Columns1. Place column in the magnetic field of a suitable MACSSeparator. For details refer to the respective MACS Columndata sheet.2.

第42 卷第 11 期2023 年11 月Vol.42 No.111469~1478分析测试学报FENXI CESHI XUEBAO（Journal of Instrumental Analysis）超高效液相色谱-串联质谱法测定化妆品中15种N-亚硝胺化合物汪毅1，梁文耀1，何国山1，陈张好2，周智明2，吴谦1，席绍峰1，谭建华1*（1．广州质量监督检测研究院，国家化妆品质量检验检测中心（广州），广东广州511447；2．广东省药品检验所，广东广州510663）摘要：采用超高效液相色谱-串联质谱（UPLC-MS/MS）建立了化妆品中15种痕量N-亚硝胺化合物的分析方法。
水剂样品以水或乙腈分组超声提取，膏霜乳液样品采用亚铁氰化钾-乙酸锌溶液沉淀大分子或者饱和氯化钠-乙腈盐析分组处理后，以Agilent Poroshell 120 SB-Aq（100 mm×3.0 mm，2.7 μm）色谱柱分离，经大气压化学电离源（APCI）电离，多反应监测模式检测，以同位素内标法定量。
结果表明，15种N-亚硝胺化合物在相应质量浓度范围内线性关系良好（r2＞0.995），检出限和定量下限分别为5~15 ng/g和15~45 ng/g。
水、乳、膏霜3种化妆品基质在25、50、100 ng/g加标水平下的平均回收率为88.0%~111%，相对标准偏差（RSD，n=6）为1.4%~9.8%。
该方法用于市售化妆品检测，发现13批次样品检出N-亚硝基二乙醇胺（NDELA），其中1批次超限量值。
方法的专属性强，灵敏度高，精密度好，解决了N-亚硝胺化合物稳定性差、易被干扰等问题，适用于化妆品中15种N-亚硝胺化合物的痕量测定。

The final estab⁃lished method involved ultrasonic extraction of cosmetics using water or acetonitrile for different com⁃pounds. The samples were treated with potassium ferrocyanide-zinc acetate solution for precipitating macromolecules or saturated sodium chloride-acetonitrile for salting out.An Agilent Poroshell 120 SB-Aq（100 mm × 3.0 mm，2.7 μm） chromatography column was used for separation，followed by atmospheric pressure chemical ionization（APCI） source and multiple reaction monitoring mode detec⁃tion in the isotope internal standard method for quantification. The result showed good linearity（r2> 0.995） for the 15 N-nitrosamine compounds in their respective concentration ranges，with detection and quantitation limits of 5-15 ng/g and 15-45 ng/g，respectively.The average recoveries for the three cosmetic matrices（aqueous，emulsion，cream） at spiked levels of 25，50，100 ng/g were be⁃tween 88.0% and 111%，with relative standard deviations（RSD，n=6） of 1.4%-9.8%. The method was applied to the detection of commercial cosmetics and N-nitrosodiethanolamine（NDELA） was de⁃tected in 13 batches，with one batch exceeding the limit. The strong specificity，high sensitivity，and good precision made the method could solve the problems of poor stability and easy interference ofdoi：10.19969/j.fxcsxb.23051602收稿日期：2023－05－16；修回日期：2023－06－10基金项目：广东省药品监督管理局化妆品风险评估重点实验室专项（2021ZDZ03）；广东省市场监督管理局科技项目（2022CZ06）∗通讯作者：谭建华，博士，正高级工程师，研究方向：色谱－质谱检测技术研究，E-mail：tanjianhua0734@第 42 卷分析测试学报N-nitrosamine compounds，and was suitable for the trace determination of 15 N-nitrosamine com⁃pounds in cosmetics.Key words：N-nitrosamine compounds；cosmetics；ultra performance liquid chromatography-tan⁃dem mass spectrometry（UPLC-MS/MS）；atmospheric pressure chemical ionization（APCI） sourceN-亚硝胺化合物是一类具有N-亚硝基结构的化合物，因取代基的不同，形成了种类繁多的同系物，目前已发现超过300种［1］。

Mechanisms: Pathways:Others; Target:Others g y Biological Activity: ITE is a aryl hydrocarbon receptor (AhR) agonist with Ki of 3 nM, and the estimated IC50 of ITE for OVCAR-3 cell proliferation was 0.2 nM. IC50 value: 0.2?nM (for OVCAR-3 cell), 3 nM (Ki) [1] Target: AhR in vitro: ITE is the endogenous high-affinity AhR agonist, possesses potent anticancer activity but the mechanism of action remains unclear. ITE enhances the binding of the AhR to the promoter of Oct4 and suppresses its transcription. ITE is presumably high enough in exerting its biological [1] ] functions. [ in vivo: ITE is a potential compound to induce functional FoxP3+ Treg in vivo and treat autoimmune diseases.[2]... References: [1]. Cheng J, et al.
