丙烯葡聚糖凝胶S-300 HR BR 进口原装 英文名称:Sephacryl S-300 High resolution CAS号:65546-95-4 Useful fractionation range(MW):globular proteins 1×10∧4~1.5×10∧6;dextrans 2×10∧3~4×10∧5 DNA exlusion limit(base pairs):118 Bead form:Spherical,diameter 25-75um in wet form Bead structure:Allyl dextran and N,N-methylene bisacrylamide pH stability:long term 3~11,short term 2~13 Chemical stability:Stable to all commonly used fuffers:0.2M NaOH;0.1M HC1;1M acetic acid;8M urea;6M guanidine HC1;1% SDS;2M NaC1;24% ethanol;30% propanol;30% acetonitrile(tested at 40℃ for 7 days) Physical stability:Negligible volume variation due to changes in pH or ionic strength 性状:乳白色液体 用途:For size exclusion chromatography; the HR grade is a smaller particle size with narrower size range distribution, allowing for more efficient separations at faster flow rates. Recommended fractionation ranges are listed for globular proteins and dextrans 保存:2~8℃
