使用方法
Guidance for conjugation of Fluorophore-NHS with protein: Step 1 Solutions & buffers 1 M Sodium Phosphate Buffer, pH 7.0 10x NaH2PO4 1 M 125 ml Na2HPO4 1 M 875 ml Reaction buffer Sodium Phosphate buffer (pH 7.0) 0.1 M 100 ml KOAc(pH 7.4) 75 mM 37.5 ml DTT 2 mM 2 ml Step 2 Make a 20 mM stock of Fluorophore-NHS (e.g. CY7-NHS) in DMSO Step 3 Enzyme storage buffer HEPES–KOH (pH 7.4) 20 mM 20 ml KOAc (pH 7.4) 100 mM 50 ml DTT 2 mM 2 ml Glycerol 10% 100 ml Preparation: Pure lyophilized protein can be dissolved in reaction buffer to a final concentration of >2.0 mg ml-1. If the protein is already in solution, it should be brought into reaction buffer by dialyzing overnight at 4°C against 2 l reaction buffer, by gel filtration, or by repeated buffer exchange through a protein concentrator of desired MWCO (M
产品功能
CY7-SE, also called CY7-NHS, is consist of two parts, the fluorophore CY7 and the reactive group N-Hydroxysuccinimide (NHS). When proteins conjugated with CY7-NHS through the reaction of NHS with the amine groups, the proteins are labeled with CY7 with excitation wavelength of 750 nm and emission wavelength of 773 nm.
