Background: Transforming Growth Factor β-1 (TGFβ-1) is a secreted protein which belongs to the TGF-β family. TGFβ-1 is abundantly expressed in bone, articular cartilage and chondrocytes and is increased in osteoarthritis (OA) . TGFβ-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 TGFβ-1 peptide. TGFβ-1 may also form heterodimers with other TGFβ family members. It has been found that TGFβ-1 is frequently upregulated in tumor cells. Mutations in this gene results in Camurati-Engelmann disease.

Description: 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.

Alternate Names: Transforming Growth Factor Beta-1, TGF-Beta-1, Latency-Associated Peptide, LAP, TGFB1, TGFB

Purity: Greater than 95% as determined by reducing SDS-PAGE.

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.

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.

Molecular Weight: 14.6 KDa

Observed Molecular Weight: 12-18 KDa, reducing conditions

Storage: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.

Storage Conditions: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.

Delivery Condition: The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.
