Chondroitin Sulfate Sodium consists mostly of the sodium salt of the sulfate ester of N -acetylchondrosamine (2-acetamido-2-deoxy-β-D -galactopyranose) and D -glucuronic acid copolymer. These hexoses are alternately linked β-1,4 and β-1,3 in the polymer. Chondrosamine moieties in the prevalentglycosaminoglycan are monosulfated primarily on position 4 and less so on position 6. It contains NL T 90.0% and NMT 105.0% of chondroitin sulfate sodium, calculated on the dried basis.[N OTE — Chondroitin Sulfate Sodium is extremely hygroscopic once dried. Avoid exposure to the atmosphere, and weigh promptly.]IDENTIFICATION•A. I NFRARED A BSORPTION 〈197K 〉•B.

By peak-area response, ΔDi-4S is the most abundant, followed by ΔDi-6S, with ΔDi-0S being the least abundant of the three. The ratio of the peak response of the ΔDi-4S to the ΔDi-6S is NL T 1.0.•D.

The hazard is increased by the use of aqueous buffer solutions and the possibility of working in damp environments. The equipment, with the possible exception of the power supply, should be enclosed in either a grounded metal case or a case made of insulating material. The case should have an interlock that deenergizes the power supply when the case is opened, after which reactivation should be prevented until activation of a reset switch is carried out. High-voltage cables from the power supply to the apparatus should preferably be a type in which a braided metal shield completely encloses the insulated central conductor, and the shield should be grounded. The base of the apparatus should be grounded metal or contain a grounded metal rim that is constructed in such a way that any leakage of electrolyte will produce a short that will deenergize the power supply before the electrolyte can ow beyond the protective enclosure. If the power supply contains capacitors as part of a lter circuit, it should also contain a bleeder resistor to ensure discharge of the capacitors before the protective case is opened. A shorting bar that is activated by opening the case may be considered as an added precaution. Because of the potential hazard associated with electrophoresis,laboratory personnel should be completely familiar with electrophoresis equipment before using it.]Barium acetate buffer:Dissolve 25.24 g of barium acetate in 900 mL of water. Adjust with acetic acid to a pH of 5.0, and dilute with water to 1000 mL.Staining reagent:Dissolve 1 g of toluidine blue in 1000 mL of 0.1 M acetic acid.Standard solution A:30 mg/mL of USP Chondroitin Sulfate Sodium RS in waterU UStandard solution B:Dilute 1 mL of Standard solution A with water to 50 mL.Sample solution:30 mg/mL of Chondroitin Sulfate Sodium in waterAnalysis:Fill the chambers of an electrophoresis apparatus suitable for separations on cellulose acetate membranes (a small submarine gel chamber or one dedicated to membrane media) with Barium acetate buffer . Soak a cellulose acetate membrane, 5–6 cm × 12–14 cm, in Barium acetate buffer for 10 min, or until evenly wetted, then blot dry between two sheets of absorbent paper. Using an applicator suitable for electrophoresis, apply equal volumes (0.5 µL) of Standardsolution A , Standard solution B , and Sample solution to the brighter side of the membrane held in position in an appropriate applicator stand or on a separating bridge in the chamber. Ensure that both ends of the membrane are dipped at least 0.5–1.0 cm deep into the buffer chambers. Apply a constant 60 V (6 mA at the start) for 2 h.[N OTE —Perform the application of solutions and voltage within 5 min because further drying of the blotted paper reduces sensitivity.]Place the membrane in a plastic staining tray, and with the application side down, oat or gently immerse in Staining reagent for 5 min. Then stir the solution gently for 1 min. Remove the membrane, and destain in 5% acetic acid until the background clears. Compare the bands. [N OTE —Document the results by taking a picture within 15 min of completion of destaining.]Acceptance criteria:The electropherogram from the Sample solution exhibits a major band that is identical in position to the band from Standard solution A . The band from Standard solution B is clearly visible at a mobility similar to the band from Standard solution A . Any secondary band in the electropherogram of the Sample solution is not more intense than the band from Standard solution B . NMT 2% of any individual impurity is found.

The working concentration of the chondroitinase AC in Buffer solution must be su cient for a complete digestion and meet the enzyme suitability requirement that follows.[N OTE —If Chondroitinase AC from Arthrobacter auresens is used, 0.2 Units/mL in Buffer solution is a typical working concentration; if Chondroitinase AC fromFlavobacterium heparium is used, 3 Units/mL in Buffer solution is a typical working concentration. The working enzyme concentration may be increased if a complete digestion could not be achieved.

donor in bone cell mineralization studies [1][3]. In MC3T3-E1, ROS 17/2.8, and chick osteoblast-like cells, β-Glycerophosphate did not affect the rate of anaerobic glycolysis, but increased the medium Pi levels, suggesting that β-Glycerophosphate was hydrolyzed by bone cells. The local increase in medium Pi concentration promoted rapid mineral deposition [1]. In human bone marrow stromal cells (HBMSC) and human osteoblasts (HOB), BMP-2 resulted in mineralization of their matrix in the presence of beta-glycerophosphate and ascorbic acid [3]. β-Glycerophosphate (10 mM) also accelerated calcification of cultured vascular smooth muscle cells through an alkaline phosphatase-related mechanism [4]. 参考文献:
产品描述:
β-Glycerophosphate (sodium salt hydrate) is a potent protein phosphatase inhibitor [1]. Protein phosphatase is an enzyme that removes a phosphate group from the phosphorylated amino acid residue of its target protein. Protein phosphorylation is one of the most common protein posttranslational modifications. β-Glycerophosphate is a potent protein phosphatase inhibitor that acts as a phosphate group
