Background

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.

FAQs for Collagen I alpha 1 Antibody (MAB6220). (Showing 1 - 4 of 4 FAQ).

1. We are looking for an anti-Collagen antibody for Flow Cytometry (FACS) analysis in Swine sample. Would you please provide some references if there is any available as well?
   • We currently have one antibody for porcine Collagen validated in flow cytometry (catalog # NBP1-94202).
2. I am looking for anti collagen 1 antibody, I see your product calls it collagen I alpha 1 is there a difference?
   • Collagen I alpha 1 is the most common protein for the collagen 1 protein. There are other subunits as well (such as collagen 1 alpha 2…etc.).
3. The predicted molecular weight says 150kDA but the band on the gel appears at 130kDA why is that?
   • Differences between the predicted and observed MW can be affected by a number of factors including PTMs, relative charges and experimental factors. These cumulative effect of these differences can be quite substantial with larger molecules such as collagen I alpha 1.
4. How long does delivery take for your collagen 1 alpha 1 antibody?
   • Our most popular collagen I alpha 1 antibody (NB600-408) is usually in stock and ships priority overnight for next business day delivery in the U.S.
