Single Step KRX Competent Cells

Efficient transformation and tightly controlled protein expression. Ideal for rapidly generating new clones for recombinant protein expression.

Regulated Mammalian Expression System

Allows high levels of controlled induction with low basal protein expression, and gives you the convenience of a rapid and sensitive on/off switch for protein expression.

FastBreak™ Cell Lysis Reagent

FastBreak™ Cell Lysis Reagent is designed for the efficient, gentle lysis of E. coli cultures without the need for centrifugation or mechanical cell disruption. The reagent is provided as a 10X concentrate. Add the reagent directly to E. coli cultures. Following a brief incubation, the cells are disrupted, and the protein of interest is released.
