Description
Details
Description:Mouse monoclonal antibody to human Transforming Growth Factor beta (TGF-β)
Purification: Protein G affinity purified
Product Type:Primary antibody
Target Protein:Human TGF-β
Immunogen:TGF-βfrom human platelets
Fusion Myeloma: Sp2/0-Ag14
Specificity:Western blotting demonstrated that this antibody reacts with the dimeric (25 kDa) and monomeric (12.5 kDa.) forms of TGF-β under both non-reducing and reducing conditions respectively. This antibody recognizes both human platelet-derived and recombinant TGF-β in ELISA.
Species Reactivity: Human, others not tested.
Host / Isotype: Mouse, IgG1 Kappa
Formulation: Lyophilized in 0.01M PBS, pH 7.0.
Reconstitution:Double distilled water is recommended and to adjust the final concentration to 1.00mg/mL.
Storage: Store at -20oC
Research Area:Growth Factors and Their Receptors, Angiogenesis
Background:
Transforming growth factor beta (TGF-β) has three isoforms (TGF-β1, TGF-β2, and TGF-β3) with similar functions.
The cytokine is a homodimer linked by disulfide bind. Inside cells, the cytokine forms a small latent complex with latent associated peptide (LAP). This small complex binds to latent TGF-β binding protein (LTBP) to be secreted to extra-cellular matrix. Disassociation of the latent proteins from TGF-β results in the release of the cytokine to its receptor. The process is called activation, which can be influenced by various factors, including proteases, metalloproteases, extreme pH, mild acidic condition, reactive oxygen species and integrins.
TGF-β is an anti-proliferation factor in normal cells. It increases the synthesis of p15 and p21, which can block the cyclin: CDK complex, and causes cells to stop at G1 phase. The cytokine can induce apoptosis through both SMAD and DAXX pathways. In cancer cells, TGF-β signaling is altered and TGF-β no longer stops cell proliferation.
Applications:
ELISA: The antibody reacts with TGF-β.
Western Blot: This antibody when used at concentration of 5-20ng/mL will allow visualization of 100ng/lane of TGF-β.

由于质粒的不兼容性,拥有同种复制子的质粒不能在同一细胞内稳定共存,经过几代的复制,会质粒丢失,所以并不是任何两个或两个以上质粒都可以在同一细胞内稳定存在,但是可以同时进入.
稳定转染的细胞株，就是转染后质粒可以稳定整合到基因组上不会因细胞分裂而丢失。区别于质粒瞬时转染不能长时间保留质粒在细胞里。
推荐了解“主细胞库”“工作细胞库”这两个名词。
对于瞬时转染的检测：如果有报告基因，就通过报告基因的表达看转染成功与否；没有报告基因的话，就在24～96h内收获细胞通过RT-PCR和WB来鉴定。
