Human collagen type I protein purified from human placenta


Human placenta. Negative for HBsAg, HCV, HIV1 and HIV2


Human collagen type I at least 90%, human collagen type III below 10%. Other human collagens and non-collagen proteins below 1%. Purity is controlled by SDS-PAGE and by ELISA with anti-collagen type-specific antibodies




Partial pepsin digestion in acidic conditions, differential salt precipitation and DEAE ion-exchange chromatography


Human collagen type I standard e.g. for ELISA and dot blotting (3, 4, 5, 6)

Antigen for antibody production

Coating material for cell culture studies (7)

Glycation of collagen type I, coating at 10 ug/cm2 and adhesion of pancreatic islet-derived mesenchymal stem cells (PI-MSCs) (7)

Collagen type I was used in cell substrates to various stiffness. Cell topography (HFF, human glioblastoma cell line U87, human foreskin fibroblast) depends on substrate stiffness and 3D microenvironment (8)

Cell attachment assay (9)

The zona pellucida of a blastocyst-stage human embryo was plated on 10 ng/ml collagen type I (10)

Collagen type I rescue experiments (11)

Application notes: Cell attachment assay

HeLa cell are detached by non-enzymatic dissociation buffer and reseeded onto 96-well polystyrene plate coated with 40 ug/ml collagen I (CC050, Millipore) for 30 mins. After the non-adherent cells were washed away by DMEM media, the remaining attached cells were quantified by crystal violet-based spectrophotometric method.


Use 0.1 M acetic acid, pH 3.0


Shipping at ambient temperature. Storage 2 years at -20°C or lower
