Biologically Active Proteins

bioactive 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.
