Background

Collagen type IV is a type of collagen found primarily in the basal lamina. The type IV collagen C4 domain at the C-terminus is not removed in post-translational processing, and the fibers link head-to-head, rather than in parallel. Also, collagen type IV lacks the regular glycine in every third residue necessary for the tight, collagen helix. This makes the overall arrangement more sloppy with kinks. These two features cause collagen IV to form in a sheet, the form of the basal lamina. There are six human genes associated with collagen IV: COL4A1, COL4A2, COL4A3, COL4A4, COL4A5 and COL4A6.

Target Details

COL4A1-COL4A6  - View All COL4A1-COL4A6 Products
This product has been prepared from human placenta and is chromatographically and immunologically pure.  This product is free from other collagens, human serum proteins and non-collagen extracellular matrix proteins.  This product reacts with anti-Collagen Type IV.  Reaction with Rockland’s anti-Collagen I, II, III, V or VI is negligible.

Application Details

SDS-PAGE
ELISA  - View References
Collagen type IV has been tested in SDS-Page and can be used as a control or standard in indirect trapping ELISA for quantitation of antigen using a standard curve, for immunoprecipitation and for other immunological assays as optimized by the user. Specific conditions should be optimized by user.

What is the source of the collagen proteins?

Collagen proteins are purified from various sources including bovine or human placenta, skin, nasal tissue, and knee cartilage. The purity of the protein is analyzed by SDS-PAGE.

How are the collagen proteins purified?

The proteins were purified by a proprietary method that includes mechanical separation and salt precipitation. Due to the nature and close association of certain collagen proteins, it is difficult to fully separate each collagen.

In what format are the collagen proteins provided?

Collagen proteins are provided in liquid format at a concentration of around 1 mg/mL. The collagen proteins are solubilized, maintaining their native structure. No enzymatic treatment is performed. The low pH of the buffer is essential in maintaining the solubility of the collagen protein.

In what buffer are the collagen proteins provided?

0.5 M Acetic Acid, pH 2.5 with 0.01% (w/v) Sodium Azide.

What are the recommended SDS-PAGE conditions for collagen proteins?

The recommended buffer for SDS-PAGE is 2X SDS buffer with 8 M Urea. The low pH of the buffer maintains the solubility of the collagen proteins. Also, low-density gels such as 3-8% Tris Acetate should be used. Collagen proteins can be reduced with DTT.

What are the recommended storage conditions for collagen proteins?

Collagen proteins should always be stored at 4°C. It is important to never let the collagen proteins freeze because this will degrade the protein. Please be sure to maintain 4°C temperature during assays such as SDS-PAGE.

How was the concentration determined?

The concentration of the collagen proteins was measured by absorbance via nanodrop at 205 nm. When measuring concentration, please be sure to blank with the same buffer as the protein product (0.5 M Acetic Acid).

Are collagen proteins suitable for cell culture?

Since no testing for endotoxin or other contaminants was performed, we do not recommend the use of this product for cell culture.
