Cocamidopropyl betaine (CAPB) is an organic compound derived from coconut oil and dimethylaminopropylamine.It is a zwitterion, consisting of both a quaternary ammonium cation and a carboxylate. CAPB is available as viscous pale yellow solution that is used as a surfactant in personal care products.The name reflects that the major part of the molecule, the lauric acid group, is derived from coconut oil.APB is available as viscous pale yellow solution that is used as a surfactant in personal care products. The name reflects that the major part of the molecule, the lauric acid group, is derived from coconut oil.
Isopropyl Î²-D-1-thiogalactopyranoside (IPTG) is a molecular biology reagent.This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator.or induction, a sterile, filtered 1 M solution of IPTG is typically added by 1:1000 dilution into a logarithmically growing bacterial culture, however, different final concentration of IPTG may also be used.
