Useful for solubilizing membrane proteins and breaking protein-protein interactions. CHAPS’ small micellar molecular weight (6,150) and high critical micelle concentration (6-10 mM) allow it to be removed from samples by dialysis. It is also suitable for protein solubilization for isoelectric focusing and two-dimensional electrophoresis. CHAPS is commonly used for non-denaturing (without urea) IEF and has been shown to give excellent resolution of some subcellular preparations and plant proteins. Concentrations between 2-4% (w/v) are typically used in an IEF gel. 性质 description zwitterionic product line BioXtra assay ≥98% (TLC) mol wt micellar avg mol wt 6150 aggregation number 10 total impurities ≤0.001% Phosphorus (P)   ≤0.1% Insoluble matter ign. residue ≤0.1% CMC 6 mM(20-25°C) EQP level Elite transition temp cloud point >100 °C solubility H2O: soluble0.1 M at 20 °C, clear, colorless anion traces chloride (Cl-): ≤0.05% cation traces Al: ≤0.0005%   Ca: ≤0.0005%   Cu: ≤0.0005%   Fe: ≤0.0005%   K: ≤0.005%   Mg: ≤0.0005%   NH4+: ≤0.05%   Na: ≤0.005%   Pb: ≤0.001%   Zn: ≤0.0005% 安全性 Hazard Codes T Risk Statements 61 Safety Statements 53-45 WGK Germany NWG
