產(chǎn)品描述：Recombinant Human Transforming Growth Factor beta 1 is produced by our Mammalian expression system and the target gene encoding Ala279-Ser390 is expressed.

別名：TGFB1蛋白;Transforming Growth Factor Beta-1, TGF-Beta-1, Latency-Associated Peptide, LAP, TGFB1, TGFB

來源：CHO Stable Cells

形態(tài)：Lyophilized from a 0.2 μm filtered solution of 50mM Glycine-HCl, 150mMNacl, pH2.5.

序列：ALDTNYCFSSTEKNCCVRQLYIDFRKDLGWKWIHEPKGYHANFCLGPCPYIWSLDTQYSKVLALY NQHNPGASAAPCCVPQALEPLPIVYYVGRKPKVEQLSNMIVRSCKCS

內(nèi)毒素水平：Less than 0.01 EU/ug as determined by LAL test.

活性：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.

溶解方法：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. 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.

保存方法：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.

背景說明：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.
