Caratteristiche e vantaggi
- Da coda di ratto.
- Sottoposto a filtrazione sterilizzante per ridurre al minimo il rischio di contaminazione.
- Qualificato per un ampio spettro di applicazioni per colture cellulari
- Garantisce un′ottima copertura superficiale (6-10 μg/cm2) per promuovere l′adesione e la proliferazione cellulare.
Nota sulla preparazione
L′analisi con elettroforesi su gel di poliacrilammide con SDS mostra la tipica configurazione a banda del collagene di tipo I, con un doppione ai pesi molecolari apparenti di 115 e 130 kDa e un altro a 215 e 235 kDa. Sulla base di questa analisi, la purezza del campione di collagene è >95%.

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 risposta-
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.Utile?

In what volume should I dilute this solution in order to make collagen-coated plates for tissue culture?
1 risposta-
The recommended surface coverage for this product is 6?10 μg/cm2. Collagen solutions may be diluted to a working concentration of 0.01%. A general collagen coating protocol is available at https://www.sigmaaldrich.com/technical-documents/technical-article/cell-culture-and-cell-culture-analysis/mammalian-cell-culture/collagen-product-protocols

How can I make a 3-D collagen gel?
1 risposta-
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.

How does the storage temperature relate to shipping conditions?
1 risposta-
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.
