Design Changes in Chip Revision v3.0 1.Design Changes in ChipRevision v3.0Espressif has released ESP32 chip revision v3.0 that features wafer-level changes basingon previous ESP32 chip revisions. The design changes introduced on the ESP32 chiprevision v3.0 are:1.Fixed "Due to the flash start-up time, a spurious watchdog reset occurs when ESP32 ispowered up or wakes up from Deep-sleep". Details of the issue can be found in item 3.8in ESP32 Series SoC Errata.2.PSRAM Cache Bug Fix: Fixed “When the CPU accesses the external SRAM in a certainsequence, read & write errors can occur”. Details of the issue can be found in item 3.9 inESP32 Series SoC Errata.3.Fixed “When each CPU reads certain different address spaces simultaneously, a readerror can occur”. Details of the issue can be found in item 3.10 in ESP32 Series SoCErrata.4.Optimized 32.768 KHz crystal oscillator stability. The issue was reported by client thatthere is a low probability that on chip revision v1.0 hardware, the 32.768 KHz crystaloscillator couldn’t start properly.5.Fixed Fault injection issues regarding secure boot and flash encryption are fixed.Reference: Security Advisory concerning fault injection and eFuse protections(CVE-2019-17391) & Espressif Security Advisory Concerning Fault Injection and SecureBoot (CVE-2019-15894)6.Improvement: Changed the minimum baud rate supported by the TWAI module from 25kHz to 12.5 kHz.7.Allowed Download Boot mode to be permanently disabled by programming new eFusebit UART_DOWNLOAD_DIS.

ChIP实验精讲(做科研的必看)

ChIP实验精讲(做科研的必看)染色质免疫共沉淀(ChIP)概述ChIP:chromatinimmunoprecipitation assay,染色质免疫沉淀技术。

研究蛋白质与DNA在染色质环境下的相互作用是阐明真核生物基因表达机制的基本途径。

ChIP是目前唯一研究体内DNA与蛋白质相互作用的方法原理在活细胞状态下固定“蛋白质-DNA”复合物,并将其随机切断为一定长度范围内的染色质小片段,然后通过免疫学方法沉淀此复合体,特异性地富集目的蛋白结合的DNA片段,通过对目的片断的纯化与检测,从而获得蛋白质与DNA相互作用的信息。

ChIP应用1、检测体内反式因子与DNA的动态作用,研究组蛋白的各种共价修饰与基因表达的关系;2、CHIP与基因芯片相结合建立的CHIP-on-ChIP 方法已广泛用于特定反式因子靶基因的高通量筛选;3、CHIP与体内足迹法相结合,用于寻找反式因子的体内结合位点;4、RNA-CHIP用于研究RNA在基因表达调控中的作用。

Perform cell lysis at 4°C.Keep the samples ice-cold and use ice-cold buffers.Under/over cross-linkingPlease note: When using paraformaldehyde, ensure that it is freshly prepared (final concentration of 1%–1.5%).–Under cross-linking can prevent the disassociation of protein–DNA complexes and result in poor yield.–Over cross-linking can mask epitope sites crucial for antibody binding, prevent chromatin shearing, and inhibit the successful uncross-linking of the protein–DNA complex.TECH TIPS FOR ChIP EXPERIMENTSChIP Tip 3:Chromatin shearing and sonication–Avoid large fragments in the tissue suspension.–Pipette with cut tips for better homogenization.–Ensure the sonicator probe is not in contact withthe tube wall.–Increase the number of sonication steps; however,avoid increasing the time (or the power) of eachstep as this may overheat the sample and lead toloss of antigenicity.–Add ice to the sonicator to avoid the sample overheating.TECH TIPS FOR ChIP EXPERIMENTSChIP Tip 4:Bead and primary antibody choice (Beads)–Always fully resuspend beads by vortexing before pipetting.–Always store at 4°C and never allow beads to dry out.–Check the subclass of your antibody is compatible withProtein A/G.Affinity of human immunoglobulins to Protein A and G Binding Capacity:++++ Strong Binding +++/++ Medium Binding Variable/– Weak orNo BindingThe full table of human, mouse, rat and guinea pig immunoglobins can be found in our technical guide “Overview & Technical Tips: Immunoprecipitation”.To download click hereTECH TIPS FOR ChIP EXPERIMENTSChIP Tip 4:Bead and primary antibody choice (Antibody)–Verify your antibody of interest is ChIP validated.–Insufficient amount of antibody can result in notenough material for successful PCR analysis.–Too much antibody can increase PCR background.Negative ChIP controls–Use non-immune IgG in the IP incubation mix fromthe same species the antibodies were produced in.–Incubate IP fraction with beads (without antibody coating).TECH TIPS FOR ChIP EXPERIMENTSChIP Tip 5: ChIP Tip 6:IP efficiency in reverse cross-linking IP–Usually, a 15-minute incubation at 95°C is sufficient.Some samples require Proteinase K treatment for four or more hours at 65°C.DNA elution and purification–Use different washing buffers (low & high salt, LiCl nd TE buffers).–While using a commercial purification column, check the column is completely dry after the wash step as any leftover moisture will inhibit elution.–Make sure the elution buffer is placed directly onto the silica membrane and allowed to adsorb for atleast one minute.TECH TIPS FOR ChIP EXPERIMENTSChIP Tip 7:Analysis on Immunoprecipitated DNA–To avoid variations between replicates, add the sameamount of protein G/A-agarose or magnetic beads for allsamples. Ensure beads are well suspended while pipetting.–Complete the elution of chromatin from protein G/A beads.Elution is optimal at 65°C with frequent mixing to keep beadssuspended in solution (~10 minutes).Please note: A weak PCR signal or no DNA amplification shownin the samples may be due to an inadequate primer result in thePCR amplified region spanning the nucleosome-free region.11Tech Tips For Successful ChIP Experiments CONTACT US*********************************************************Available 24 hours via Live Chat and 9–5 (CDT) via phone.Proteintech Group Proteintech Europe Proteintech Support US Head OfficeUnited KingdomChina OfficePlease visit us at for more information about our antibodies and technical tips.。

Microchip offers a broad portfolio of stand-alone analog and interface solutions that address the thermal management, power management, mixed-signal, linear, interface and safety and security markets.In addition to using low power CMOS technology, Microchip’s analog products are designed to optimize performance while minimizing power consumption.Non-volatile expertise is leveraged to achieve high accuracy specifications without additional manufacturing steps and cost. Chip select/shutdown/sleep features on many of our analog and interface parts enable systems to be selectively shut down to further reduce power consumption.Low operating voltages combined with small form factors such as SC70, DFN and SOT-23 make Microchip’s analog and interface portfolio well-suited for applications with tight power budgets.Typical Applications■Battery powered/Handheld■Consumer■PC Peripherals■Telecommunication■Automotive■IndustrialDesign Tools■CAD/CAE Schematic Symbols and Footprints/cadProduct Selection Tools■Microchip’s Advanced Product Selector/MAPS■Treelink presentation/treelinkStand-Alone Analog and Interface Portfolio Low Power Analog SolutionsPower Management LDO & Switching Regulators Charge PumpDC/DC Converters Power MOSFET DriversPWM Controllers System Supervisors Voltage Detectors Voltage References Li-Ion/Li-Polymer Battery ChargersMixed-SignalA/D ConverterFamiliesDigitalPotentiometersD/A ConvertersV/F and F/VConvertersEnergyMeasurementICsInterfaceCAN PeripheralsInfraredPeripheralsLIN TransceiversSerial PeripheralsEthernet ControllersUSB Peripheral LinearOp AmpsProgrammableGainAmplifiersComparatorsSafety & SecurityPhotoelectricSmoke DetectorsIonization SmokeDetectorsIonization SmokeDetector Front EndsPiezoelectricHorn DriversThermalManagementTemperatureSensorsFan SpeedControllers/Fan FaultDetectorsMotor DriveStepper and DC3Ф BrushlessDC Fan ControllerM i c r o c h i p T e c h n o l o g y I n c o r p o r a t e dInformation subject to change.

一、ChIP实验步骤第一天:(一)、细胞的甲醛交联与超声破碎。

1、取出1平皿细胞(10cm平皿),加入243ul 37%甲醛,使得甲醛的终浓度为1%。

(培养基共有9ml)2、37摄氏度孵育10min。

3、终止交联:加甘氨酸至终浓度为0.125M。

450ul 2.5M甘氨酸于平皿中。

混匀后,在室温下放置5min即可。

4、吸尽培养基,用冰冷的PBS清洗细胞2次。

5、细胞刮刀收集细胞于15ml离心管中(PBS依次为5ml,3ml和3ml)。

预冷后2000rpm 5min收集细胞。

6、倒去上清。

按照细胞量,加入SDS Lysis Buffer。

使得细胞终浓度为每200ul含2×106个细胞。

这样每100ul溶液含1×106个细胞。

再加入蛋白酶抑制剂复合物。

假设MCF7长满板为5×106个细胞。

本次细胞长得约为80%。

即为4×106个细胞。

因此每管加入400ul SDS Lysis Buffer。

将2管混在一起,共800ul。

7、超声破碎:VCX750,25%功率,4.5S冲击,9S间隙。

共14次。

(二)、除杂及抗体哺育。

8、超声破碎结束后,10,000g 4度离心10min。

去除不溶物质。

留取300ul做实验,其余保存于-80度。

300ul中,100ul加抗体做为实验组;100ul不加抗体做为对照组;100ul加入4ul 5M NaCl (NaCl终浓度为0.2M),65度处理3h解交联,跑电泳,检测超声破碎的效果。

9、在100ul的超声破碎产物中,加入900ul ChIP Dilution Buffer和20ul的50×PIC。

再各加入60ul Protein A Agarose/Salmon Sperm DNA。

4度颠转混匀1h。

10、1h后,在4度静置10min沉淀,700rpm离心1min。

11、取上清。

各留取20ul做为input。

一管中加入1ul 抗体,另一管中则不加抗体。
