General description

Collagen alpha-1(I) chain (UniProt P02452; also known as Alpha-1 type I collagen) is encoded by the COL1A1 gene (Gene ID 1277) in human. Collagen is the major component of the extracellular matrix (ECM) and forms the fibrils of tendons, ligaments, and bones. Type I collagen consists of two alpha I chains and one alpha 2 chain. Alpha-1 type I collagen is initially produced as a 1464-amino acid prepro-form with a signal peptide sequence (a.a. 1-22) and two propeptide sequences (a.a. 23-161 and a.a. 1219 –1464), the removal of which yields the mature alpha-1(I) chain. The mature alpha-1(I) chain is composed mostly of a large triple-helical region (a.a. 179-1192) sandwiched between two nonhelical segments known as the N-terminal telopeptide (a.a. 162-178; numbering based on the prepro-form) and the C-terminal telopeptide (a.a. 1193-1218; numbering based on the prepro-form). Collagen can be extracted from tissue via either enzymatic or non-enzymatic means. Collagen extracted using the proteolytic enzyme pepsin corresponds to the large triple-helical region, referred to as atelocollagen because both the N- and C-terminal telopeptides have been cleaved off by pepsin. On the other hand, collagen preparations obtained with non-enzymatic means (e.g. by acid extraction) have the intact telopeptides at both ends.


Labels carboxy-terminal pro-peptide of collagen type I. Does not stain mature collagen fibers in tissue, but rather is localized intracellularly in cells producing pro-collagen I.


Epitope: C-terminal propeptide region

Human pro-collagen I.


Immunohistochemistry Analysis: A 1:50 dilution from a representative lot detected Procollagen Type I in mouse skin, rat skin, and rat skeletal muscle tissue.
Immunocytochemistry Analysis: A representative lot detected type I procollagen immunoreactivity in human semitendinosus and gracilis tendon fibroblasts from patients undergoing reconstruction surgery after anterior cruciate ligament (ACL) rupture by fluorescent immunocytochemistry (Bayer, M.L., et al. (2012). Mech Ageing Dev. 133(5):246-254).
Flow Cytometry Analysis: A representative lot detected PICP+/CD45+ fibrocytes in lung cells from bleomycin-treated mice (Yeager, M.E., et al. (2012). Eur Respir J. 39(1):104-111).
Flow Cytometry Analysis: A representative lot detected higher numbers and percentages of circulating PICP+/CD45+ fibrocytes in peripheral blood samples from children/yound adults with pulmonary hypertension (PH) than in samples from healthy individuals (Reese, C., et al. (2014). Front Pharmacol. 5:141).
Immunohistochemistry Analysis: A representative lot detected cytoplasmic type I procollagen immunoreactivity in stromal cells from the lysed functionalis of frozen human menstrual endometria sections (Gaide Chevronnay, H.P., et al. (2009). Endocrinology. 150(11):5094-5105).
ELISA Analysis: A representative lot detected different age-dependency of procollagen type I C-terminal propeptide (PICP) immunoreactivity in the cruciate ligaments of osteoarthritis-/OA-prone Dunkin-Hartley (DH) guinea pigs and in age-matched Bristol strain 2 (BS2) control guinea pigs (Quasnichka, H.L., et al. (2005). Arthritis Rheum. 52(10):3100-3109).
