Recombinant Human TGFBR1 Protein (Ala25 or Leu34-Glu125), C-hFc and Avi-tagged, Biotinylated
Product Description
Cat
IMP-10075
Official Symbol
TGFBR1
Product Overview
Biotinylated recombinant human TGF-beta RI/ALK-5 protein (Ala25 or Leu34-Glu125) with a Human IgG1 (Pro100-Lys330) Fc tag and Avi-tag at C-terminus was expressed in Human embryonic kidney cell.
Description
The protein encoded by this gene forms a heteromeric complex with type II TGF-beta receptors when bound to TGF-beta, transducing the TGF-beta signal from the cell surface to the cytoplasm. The encoded protein is a serine/threonine protein kinase. Mutations in this gene have been associated with Loeys-Dietz aortic aneurysm syndrome (LDAS). Multiple transcript variants encoding different isoforms have been found for this gene.

Bio-activity
The biotin to protein ratio is greater than 0.7 as determined by the HABA assay. Measured by its binding ability in a functional ELISA. When Recombinant Human (rh) TGF-beta RII Fc Chimera is immobilized at 1 μg/mL (100 μL/well), in the presence of rhTGF-beta 1, Biotinylated Recombinant Human TGF-beta RI/ALK-5 Fc Chimera Avi-tag protein binds with an ED50 of 0.15-0.75 μg/mL.
Endotoxin
<0.10 EU/μg of the protein by the LAL method.
Purity
>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie Blue Staining.
Notes
Disulfide-linked homodimer
