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.
Less than 1.0 EU/µg protein (determined by LAL method).
The recombinant human CD47/Fc is a disulfide-linked homodimer. The reduced monomer comprises 362 amino acids and has a predicted molecular mass of 40.7 kDa. The apparent molecular mass of the protein is approximately 48-60 kDa in SDS-PAGE under reducing conditions.
The 71 amino acid recombinant protein has a predicted molecular mass of approximately 8.2 kD. The DTT-reduced and non-reduced protein migrate at approximately 11 kD and 12 kD respectively by SDS-PAGE. The predicted N-terminal amino acid is Thr.
The 65 amino acid recombinant protein has a predicted molecular mass of approximately 7.3 kD. The protein migrates at approximately 12 kD in DTT-reducing conditions and at approximately 13 kD in non-reducing conditions by SDS-PAGE. The predicted N-termina
