Biotinylated Recombinant Human Transforming Growth Factor beta 1 is produced by our Mammalian expression system and the target gene encoding Ala279-Ser390 is expressed with a Avi tag at the N-terminus.
Greater than 95% as determined by reducing SDS-PAGE.
Anwendungsbeschreibung:
Redissolve: Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100µg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.. Endotoxin: Less than 0.001ng/µg (0.01EU/µg) as determined by LAL test. Biological activity: Measured by its ability to inhibit TGF-beta 1 activity on TF-1 human erythroleukemic cells.The ED50 for this effect is 137.37pg/ml. Background: Transforming Growth Factor beta-1 (TGFbeta-1) is a secreted protein which belongs to the TGF-beta family. TGFbeta-1 is abundantly expressed in bone, articular cartilage and chondrocytes and is increased in osteoarthritis (OA). TGFbeta-1 performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation and apoptosis. The precursor is cleaved into a latency-associated peptide (LAP) and a mature TGFbeta-1 peptide. TGFbeta-1 may also form heterodimers with other TGFbeta family members. It has been found that TGFbeta-1 is frequently upregulated in tumor cells. Mutations in this gene results in Camurati-Engelmann disease
