General description
Collagen is an extracellular matrix protein comprising triple helical structure. The structure of collagen type I, in particular, is characterized by the presence of three identical α-chains in its homotrimetric form. Among these three α-chains, one exhibits slight sequence variation. Type I collagen was first isolated from rat-tail tendon, has two main α chains (α and α ) and one β chain.
Application
Used as a coating material to support adherent cells growth and differentiation.
Collagen, Type I solution from rat tail has been used for coating culture plates and dishes for human hepatocyte HepG2 cell line and podocytes. It has also been used as a standard for total collagen content calibration curve generation for the quantification of liver extracellular matrix pre-gel.
Biochem/physiol Actions
Collagen protein is essential for the mechanical integrity of tendons and bone. Rat tail tendon collagen is used in tissue engineering especially in the generation of 3-D scaffolds based gels. It has low antigenicity and is compatible with human gingival fibroblasts and human oral keratinocytes.
Features and Benefits
- Sourced from rat tail.
- Sterile-filtered to minimize contamination risks.
- Suitable for a wide range of cell culture applications.
- Provides optimal surface coverage (6-10 μg/cm2) for promoting cell adhesion and proliferation.
Preparation Note
Recommended for use as a cell culture substratum. May not be suitable for 3-D gel formation.
Sterile solution prepared from rat tail tendons by a modification of the published extraction method 1. It is supplied as an aqueous solution in 20mM acetic acid with a protein concentration as stated on the bottle. (approx.100mg protein per vial). Protein concentration was estimated by the Biuret method 2.
SDS polyacrylamide gel electrophoresis analysis shows the typical band pattern for Type I collagen, with a doublet at apparent molecular weights of 115 and 130kDa and another doublet at 215 and 235kDa. Based on this analysis, the purity of the collagen sample is >95%.

Other Notes
Collagen is classified into a number of structurally and genetically distinct types. We use the nomenclature proposed by Bornstein and Traub. Do not confuse Sigma type designations with recognized collagen classification types.
When C3867 is first removed from the cooler it will appear gelled. When it is allowed to come fully to 37°C it will appear as a liquid.

Can rat collagen solution be used as coating for human cells or is it better to use human collagen solutions?
1 answer-
Rat collagen solution can be used as a coating for human cells, as indicated by various publications. The following publication in PubMed suggests that rat collagen can serve as a viable alternative to human collagen for various applications in cell culture and tissue engineering. https://pubmed.ncbi.nlm.nih.gov/18203067/

Should I add collagen I to acetic acid to obtain 0.1% (w/v) collagen solution, or it's already added and I should only dilute it to working concentration which is 0.01?
1 answer-
Here are our preparation instructions:
This product is prepared from rat tail tendons by modification of a published procedure.
It is supplied as an aqueous solution in 20 mM acetic acid (~100 mg of protein per vial). Protein concentration was estimated by the biuret method.
The vial contains approximately 100 mg of protein. Volume per vial: 22–25 ml. The product ships on wet ice and storage at 2–8 °C is recommended. During shipment, or if the storage temperature for this product goes slightly below the recommended range, the product may acquire a gel-like appearance. Under such circumstances, it is possible to warm the product gently, to no more than 45 °C, in order to reconstitute the product fully, before use. Aliquots that have been diluted to a working concentration may be stored at 2–8 °C for up to 2 weeks. Do not freeze. Optimal conditions for attachment must be determined for each cell line and application.1. An appropriate volume of the collagen solution should be diluted to a working concentration of 0.01% using sterile, tissue culture grade water.
2. Coat dishes with 6-10 mg/cm2. Allow the protein to bind for several hours at room temperature or 37 °C, or overnight at 2–8 °C.
3. Remove excess fluid from the coated surface and allow it to dry overnight. If sterility has been compromised, the dried, coated surface can be sterilized easily by overnight exposure to UV light in a sterile tissue culture hood.
4. Rinse with sterile tissue culture grade water or a balanced salt solution before introducing cells and medium.Helpful?

How does the storage temperature relate to shipping conditions?
1 answer-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
