Detects human TGF-beta RI/ALK-5 in direct ELISAs and Western blots. In direct ELISAs, approximately 50% cross-reactivity with recombinant mouse TGF‑ beta RI is observed and less than 5% cross-reactivity with recombinant human (rh) TGF-beta RII and rhTGF-beta RIII is observed.
Polyclonal Goat IgG
Mouse myeloma cell line NS0-derived recombinant human TGF-beta RI/ALK-5 Leu34-Glu125 Accession # P36897
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.

Detection of Human TGF‑ beta RI/ALK‑5 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, HepG2 human hepatocellular carcinoma cell line, and Raji human Burkitt's lymphoma cell line. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Human TGF‑ beta RI/ALK‑5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3025) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). Specific bands were detected for TGF‑ beta RI/ALK‑5 at approximately 50 & 56 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
TGF-beta RI/ALK‑5 in Human PBMCs. TGF-beta RI/ALK‑5 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) stimulated with LPS and monensin using Goat Anti-Human TGF‑ beta RI/ALK‑5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3025) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (yellow; Catalog # NL001) and counterstained with DAPI (blue).

Background: TGF-beta RI/ALK-5
TGF-beta RI, also known as activin-like kinase 5 (ALK-5), is a 55 kDa type I transmembrane serine/threonine receptor kinase. It is ubiquitously expressed and forms a functional heterotetrameric signaling TGF-beta receptor complex with TGF-beta RII. The amino acid sequence of human TGF-beta RI extracellular domain is 91%, 90%, 91%, and 93% identical to that of porcine, mouse, bovine, and rat TGF-beta RI, respectively.
