一个生物素酰化试剂,可用于合成生物素-雌二醇共轭化合物,从而通过酶免疫测定法测定血浆雌二醇的浓度。
Biotin-PEG2-amine is PEG derivative containing a biotin group and a terminal primary amine group. The amine group can be coupled to carboxyl groups or 5'phosphate groups to form stable amide bonds. The hydrophilic PEG spacer increases solubility in aqueous media and increases membrane impermeability of the molecules conjugated to the biotin compound. It also helps to minimize steric hindrance involved with the binding to avidin molecules. PEG Linkers may be useful in the development of antibody drug conjugates and drug delivery methods.
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
