Recombinant Human Transforming Growth Factor beta-1/TGFbeta-1 is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (Ala279-Ser390) of Human TGFB1.
过滤
0.2 μm filtered
内毒素水平
Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
缓冲液
Lyophilized from a 0.2 μm filtered solution of 50 mM Glycine 50 mM NaCl pH 4.0.
注意事项
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
储存条件
4 °C/-20 °C/-80 °C
储存方法
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.
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.
