Scientific Data Images for Human Pro Collagen I  alpha1 Antibody

Detection of Human N-Pro Collagen I by Western Blot.

Detection of Human Pro-Collagen I alpha 1 by Western Blot.

Western blot shows lysates of human kidney tissue, human skin tissue, and human cartilage tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Pro-Collagen I alpha 1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6220) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Pro-Collagen I alpha 1 at approximately 140 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Human Collagen I by Western Blot.

Western blot shows lysates of IMR-90 human lung fibroblast cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Pro Collagen I  alpha1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6220) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). A specific band was detected for Collagen I at approximately 170 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.
Collagen I a1 antibody in IMR-90 Human Cell Line by Immunocytochemistry (ICC).

Pro-Collagen I alpha 1 in IMR‑90 Human Cell Line.

Pro-Collagen I alpha 1 was detected in immersion fixed IMR-90 human lung fibroblast cell line using Sheep Anti-Human Pro-Collagen I alpha 1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6220) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue).

Background: Collagen I alpha 1

Type I collagen is the most abundant structural protein of connective tissues such as skin, bone and tendon. It is synthesized as a procollagen molecule which is characterized by a 300 nm triple helical domain flanked by globular N- and C-terminal propeptides (1). The triple helical domain contains Gly-Xaa-Yaa triplets where Xaa and Yaa are frequently proline and hydroxyproline, respectively. The non-helical propeptides are removed by procollagen N- and C-proteinase activities so that the mature triple helices can self-assemble into collagen fibrils that provide tensile strength to tissues (1). Type I collagen is a heterotrimer that consists of two alpha1(I) chains and one alpha2(I) chain, although homotrimers consisting of three identical alpha1(I) chains have also been described (2). This recombinant mini pro-alpha 1(I) collagen consists of a shortened alpha1(I) chain with following domain structure from N- to C-terminus: N-propeptide, N‑telopeptide, the 33 most N-terminal Gly-Xaa-Yaa repeats, the 33 most C-terminal Gly-Xaa-Yaa repeats, C-telopeptide and C-propeptide. The preparation contains a mixture of the full-length molecule, pN collagen I( alpha1) and the C-terminal propeptide. This truncated pro-alpha 1(I) collagen is a substrate for procollagen N-proteinase and procollagen C-proteinase.
