Product name: |
Recombinant Human TGF-beta 1 |
Description: |
Recombinant Human Transforming Growth Factor Beta 1 is produced by our Mammalian expression system and the target gene encoding Ala279-Ser390 is expressed. |
Accession: |
P01137 |
Molecular weight: |
12.8 KDa |
Apparent molecular weight: |
13 KDa, reducing conditions |
Purity: |
Greater than 95% as determined by reducing SDS-PAGE. |
Endotoxin: |
Less than 0.01 EU/µg as determined by LAL test. |
Biological activity: |
Measured by its ability to inhibit the IL-4-dependent proliferation of TF‑1 human erythroleukemic cells. The ED50 for this effect is 4-40 pg/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. |
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. |
Delivery condition: |
The product is shipped at ambient temperature.
Upon receipt, store it immediately at the temperature listed below. |
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. |
