钙离子螯合剂－BAPTABAPTA及其衍生物是钙离子螯合剂（Chelators），通常用于形成有确定钙离子浓度的缓冲液。通过显微***螯合剂进入细胞或使用脂溶性的螯合剂孵育细胞，就可以人为控制胞液的钙离子浓度，是一种研究钙离子功能的重要手段。这些钙离子螯合剂***重要的优点：对于细胞内pH值变化和钙离子快速释放相对不敏感。Biotium提供好几种BAPTA螯合剂，使得钙离子解离常数覆盖了生物学上有意义的从10-7to10-2M的变化范围。订购信息：货号产品名称规格50000BAPTA,AMester25mg50000-1BAPTA,AMester20x1mg50001BAPTA,tetracesiumsalt1g50002BAPTA,tetrapotassiumsalt1g50003BAPTA,tetrasodiumsalt1g500045,5'-DibromoBAPTA,tetrapotassiumsalt100mg500055,5'-DifluoroBAPTA,AMester25mg500065,5'-DifluoroBAPTA,tetrapotassiumsalt100mg500075,5'-DimethylBAPTA,AMester25mg500085,5'-DimethylBAPTA,tetrapotassiumsalt100mg500095-methyl-5'-nitroBAPTA,tetrapotassiumsalt10mg500175-mononitroBAPTA,tetrapotassiumsalt10mg59000PluronicF-127(freesampleperorderofAMesters)1g59002EDC(EDAC;1-(3-dimethylaminopropyl-3-ethylcarbodiimide,hydrochloride))100mg59003TPEN(Fullname:tetrakis-(2-pyridylmethyl)ethylenediamine)100mg59004PluronicF-12720%solutioninDMSO1ml59005PluronicF-127,10%insterileH2O30mL59007Ionomycin,calciumsalt1mg59100CalciumCalibrationBufferKit(zeroand10mMCaEGTA,2x50mL)kit90082DMSO,anhydrous(Dimethylsulfoxide,ormethylsulfoxide)10mL)
