Scientific Data

Western Blot View Larger

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 Mouse Anti-Human N-Pro Collagen I Monoclonal Antibody (Catalog # MAB6220) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). 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.

Immunocytochemistry Collagen I a1 antibody in IMR-90 Human Cell Line by Immunocytochemistry (ICC). View Larger

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 Mouse Anti-Human Pro-Collagen I alpha 1 Monoclonal Antibody (Catalog # MAB6220) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Immunoprecipitation View Larger

Detection of Human Pro-Collagen I alpha 1 by Immunoprecipitation. Human Pro-Collagen I alpha 1 was immunoprecipitated from 500 μg of IMR‑90 human lung fibroblast cell line lysates with 5 μg of Mouse Anti-Human Pro-Collagen I alpha 1 Monoclonal Antibody (Catalog # MAB6220). The N-Pro Collagen I-antibody complexes were absorbed using Protein A or Protein G. Immunoprecipitated human Pro-Collagen I alpha 1 was detected by Western blot using 1 μg/mL of Sheep Anti-Human Pro-Collagen I alpha 1 Antigen Affinity-purified Polyclonal Antibody (AF6220) under reducing conditions and using Western Blot Buffer Group 1.

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.
