General description
Application
Biochem/physiol Actions
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
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%.

How does the storage temperature relate to shipping conditions?
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. See Shipping and Storage for more information.
How are collagen solutions stored?
Collagen solutions should be stored in the refrigerator at 2-8 °C for up to 1 year, unless it becomes contaminated.
Why am I seeing some insolubles in my collagen solution?
The solubility specifications for this product is clear to hazy colorless solution with a few insolubles at 1 mg/ml in water with 2 μl acetic acid (or 0.1 N acetic acid). The insolubles can be removed by settling or centrifugation.
How can I make a 3-D collagen gel?
Not all lots of C7661 are suitable for 3D gels. Product No. C4243 has been use-tested in this application. If C4243 is not available, we recommend that customers screen lots of C7661 to try to make 3D gels. We have found that collagen that has been sterilized by gamma-irradiation or by chloroform cannot be used to make 3D collagen gels. The following protocol can be used to make collagen gels: Materials required:Collagen gel solution 1.5 - 3 mg/mL 10X tissue culture medium containing phenol red Sodium bicarbonate or HEPES buffer Procedure: 1.Measure out 800 μL of collagen solution. 2.Add 100 μL of 10X medium (buffered with 1X sodium bicarbonate or HEPES) 3.Adjust pH with 1 N sodium hydroxide, if required (100 μl or less) 4.Add 10X medium to bring volume to 1 ml 5.Mix contents well. Solution should maintain red color to indicate physiological pH6. Dispense into wells to a depth of 1-2 mm (approx. 15 μL/well) 7.Transfer to 37 °C for 20-40 minutes 8.Examine for gel formation The above volumes represent quantities for use in 24 well plates. Volumes can be adjusted to accommodate any culture vessel.
