For PTMScan® protocols we recommend making a 5 mg/ml stock solution by resuspending 1.2 mg in 0.24 ml of 20 mM HEPES pH 8.0, aliquot for single use and store at -80°C. See the PTMScan® protocol for further details.
Store lyophilized Lys-C at -20°C. Once reconstituted, the enzyme can be aliquoted and stored at -80°C to help avoid damaging freeze thaw cycles. Lyophilized Lys-C has a shelf life of 1 year at -20°C and solutions are stable for 6 months at -80°C.
