Data Examples

Western Blot Detection of Human Collagen I a1 antibody by Western Blot. View Larger

Detection of Human 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 Collagen I a1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6220) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Collagen I a1 at approximately 140 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Collagen I alpha 1 in IMR‑90 Human Cell Line. Collagen I a1 was detected in immersion fixed IMR-90 human lung fibroblast cell line using Sheep Anti-Human Collagen I a1 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 alpha 1(I) chains and one alpha 2(I) chain, although homotrimers consisting of three identical alpha 1(I) chains have also been described (2). This recombinant mini pro-alpha 1(I) collagen consists of a shortened alpha 1(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( alpha 1) and the C-terminal propeptide. This truncated pro-alpha 1(I) collagen is a substrate for procollagen N-proteinase and procollagen C-proteinase.
