Application

A solução de colágeno tipo I da cauda de rato foi usada para revestir placas de cultura e placas para a linhagem celular de hepatócitos humanos HepG2[1] e podócitos.[2] Ela também foi usada como padrão gerar a curva de calibração de teor total de colágeno para quantificação do pré-gel da matriz extracelular hepática.[3]
Usado como material de revestimento para dar suporte ao crescimento e a diferenciação de células aderentes.

Biochem/physiol Actions

O colágeno é essencial para a integridade mecânica dos tendões e ossos. O colágeno do tendão da cauda de rato é usado na engenharia de tecidos especialmente na produção de géis à base de estruturas poliméricas tridimensionais.[4] Ele tem baixa antigenicidade e é compatível com fibroblastos gengivais humanos e queratinócitos bucais humanos.[5]

Features and Benefits

  • Obtido da cauda do rato.
  • Filtrado estéril para minimizar os riscos de contaminação.
  • Adequado para uma ampla variedade de aplicações de cultura de células.
  • Oferece cobertura de superfície ideal (6-10 μg/cm2) para promover adesão e proliferação celular.

General description

O colágeno é uma proteína da matriz extracelular que compreende uma estrutura helicoidal tripla. A estrutura do colágeno tipo I, em particular, caracteriza-se pela presença de três αcadeias idênticas em sua forma homotrimétrica. Entre essas três αcadeias, uma exibe uma leve variação de sequência.[6] O colágeno tipo I foi isolado pela primeira vez do tendão da cauda de rato, tem duas cadeias α principais (α e α ) e uma cadeia β.[5]

Other Notes

O colágeno é classificado em diversos tipos estrutural e geneticamente distintos. Usamos a nomenclatura proposta por Bornstein e Traub. Não confunda as designações de tipos da Sigma com tipos de classificação de colágeno reconhecidos.
Quando o C3867 for retirado do refrigerador pela primeira vez, ele parecerá gelatinoso. Quando a temperatura chegar totalmente a 37°C, ele aparecerá como um líquido.

Preparation Note

Solução estéril preparada a partir de tendões de cauda de rato por uma modificação do método de extração publicado 1. É fornecida como uma solução aquosa em ácido acético 20 mM com uma concentração de proteína indicada no frasco. (aproximadamente 100 mg de proteína por frasco). A concentração de proteína foi estimada pelo método de biureto 2.
A análise por eletroforese em gel de poliacrilamida com SDS mostra o padrão típico de bandas para o colágeno tipo I, com uma dubleto com pesos moleculares aparentes de 115 e 130 kDa, e outro dubleto com 215 e 235 kDa. Com base nessa análise, a pureza da amostra de colágeno é de >95%.
É recomendado para uso como substrato de cultura celular. Pode não ser adequado para formação de gel 3D.

Questions

1–10 of 10 Questions  
  1. Can rat collagen solution be used as coating for human cells or is it better to use human collagen solutions?

    1 answer
    1. 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/

  2. 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
    1. 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.

  5. In what volume should I dilute this solution in order to make collagen-coated plates for tissue culture?

    1 answer
    1. 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

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

    1 answer
    1. 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.

  8. How does the storage temperature relate to shipping conditions?

    1 answer
    1. 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.

  9. How are collagen solutions stored?

    1 answer
    1. Collagen solutions should be stored in the refrigerator at 2-8 °C for up to 1 year, unless it becomes contaminated.

  10. Why am I seeing some insolubles in my collagen solution?

    1 answer
    1. 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.
