Background Information
Type III collagen is a fibrillar forming collagen comprising three α1(III) chains and is expressed in early embryos and throughout embryogenesis (PMID: 9050868). In the adult, type III collagen is a major component of the extracellular matrix in a variety of internal organs and skin. It occurs in most soft connective tissues along with type I collagen (PMID: 2445760). COL3A1 gene encodes type III procollagen. Mutations in this gene are associated with Ehlers-Danlos syndrome types IV, and with aortic and arterial aneurysms (PMID: 10706896; 2243125; 18389341). This antibody raised against 24-152 aa of prepro α1 (III) chain of human type III procollagen detects type III procollagen at 140-180 kDa and also in some lysates reveals a 70-kDa band which has been reported and may represent a cleaved form of type III procollagen (PMID: 17424834; 19648160; 22802960).

FH Guennec (Verified Customer) (10-12-2023) | I have 2 bands at 70 KDa.
 |
FH Sarah-Eve (Verified Customer) (02-19-2023) | Works well. One band observed at 180 kDa.
|
FH Gayatri (Verified Customer) (06-10-2022) | Good signal but inexplicable molecular weight. Observe bands at 70 kDa instead of expected 140-180 kDa although this product is validated for Rat. Observed in both rat heart and tail lysates.
|
FH Yuki (Verified Customer) (03-30-2022) | Works well for IF application and presented with intense staining
 |
FH Ryan (Verified Customer) (04-20-2018) | Antibody worked well for IF application and presented with intense staining of both medial and adventitial collagen in artery sections
