Biologically Active Proteins
LSBio’s biologically active proteins have been tested to confirm that they retain their functional
attributes. Each protein is uniquely tested based upon its particular function, such as measuring
the ability of an enzyme to hydrolyze a substrate, using a cell proliferation assay to test a growth
factor, or a cytotoxicity assay to test proteins that can cause cell death. These proteins are a
cost-effective resource for use in a wide variety of in vitro research applications.
