重组人转化生长因子-β1(Human TGF-b1)

TGF b 1 Human
Transforming Growth Factor-Beta 1 Human Recombinant
Catalog No. CYT-473

Synonyms:
Transforming growth factor beta-1, TGF-beta-1, CED, DPD1, TGFB.

Introduction:
Transforming growth factor betas (TGF Betas) mediate many cell-cell interactions that occur during embryonic development. Three TGF Betas have been identified in mammals. TGF Beta 1, TGF Beta 2 and TGF Beta 3 are each synthesized as precursor proteins that are very similar in that each is cleaved to yield a 112 amino acid polypeptide that remains associated with the latent portion of the molecule.

Description:
The TGF-b 1 (177-391 a.a.) is purified by standard chromatographic techniques and shows a 51 kDa band on SDS-PAGE (including GST tag).

Source:
Escherichia Coli.

Physical Appearance:
Sterile Filtered solution at a concentration of 0.1 mg/ml.

Formulation:
The protein solution contains 50mM Tris-Acetate, pH-7.5, 1mM EDTA and 20% Glycerol.

Stability:
TGF-beta 1 although stable at 4°C for 1 week, should be stored desiccated below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

Purity:
Greater than 80.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Amino acid sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Leu-Asp-Thr-Asn.

Usage:
Prospec's products are furnished for LABORATORY RESEARCH USE ONLY. They may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
