Description générale

Gelatin from porcine skin is generated from the acidic digestion of collagen and is referred as type A. Porcine gelatin comprises majorly glycine, proline and hydroxyproline.[1] Gelatin takes up random coil structure after digestion from the triple helical collagen.[2] It differs from type B bovine gelatin at the N-terminal sequence.[3]

Application

Gelatin has been used in many applications. It has been used in coating cell culture to improve attachment of cells,[4][5] being added to PCR to stabilize Taq DNA, as a blocking reagent in western blotting, ELISA, and immunochemistry, and as a component of media for species differentiation in bacteriology. As a biocompatible polymer, it has been used as a delivery vehicle for release of active biomolecules and in generation of scaffolds for tissue engineering applications.[6] In the pharmaceutical industry, gelatin can be used as a suspending and encapsulating agent,[7] among other applications. This product is recommended for use as a cell culture substratum at 1-5 μg/cm2 or 0.5-50 μg/mL. The optimal concentration does depend on cell type as well as the application and research objectives.

Caractéristiques et avantages

  • Sterile gelatin sourced from porcine skin.
  • Free from proteases.
  • In the form of gelatin powder for convenient and easy handling.
  • Versatile for use in cell culture and electrophoresis techniques.
  • Provides adequate surface coverage for various applications.

Composants

Gelatin is a heterogeneous mixture of water-soluble proteins of high average molecular masses, present in collagen. Proteins are extracted by boiling the relevant skin, tendons, ligaments, bones, etc. in water. Type A gelatin is derived from acid-cured tissue. Type B is derived from lime-cured tissue.

Attention

Dry gelatin, when stored in airtight containers at room temperature, will remain unchanged for many years. When heated at 100°C in the presence of air, it swells becomes soft and disintegrates to a carbonaceous mass with evolution of pyridine bases and ammonia.

Notes préparatoires

This product is derived from porcine skin. Gelatin is soluble in hot than in cold water. It is practically insoluble in most organic solvents such as alcohol, chloroform, carbon disulfide, carbon tetrachloride, ether, benzene, acetone, and oils. The Bloom number, determined by the Bloom gelometer, is an indication of the strength of a gel formed from a solution of the known concentration. The Bloom number is proportional to the average molecular mass. Bloom numbers of porcine skin Gelatin vary from 90 to 300 g. This product has a gel strength of approximately 300.

Questions

1–3 of 3 Questions  
  1. What is the molecular weight of this Gelatin?

    1 answer
    1. The molecular weight of this product has not been evaluated, However, the molecular weight is closely related to the Bloom Number. The estimated ranges are as follows:
      Bloom Number Average Molecular Mass (Da)
      50−125 (Low Bloom) 20,000−25,000
      175−225 (Medium Bloom) 40,000−50,000
      225−325 (High Bloom) 50,000−100,000

  3. What is the molecular weight of gelatin from porcine skin, Type A?

    1 answer
    1. The Bloom number is proportional to the average molecular mass. Bloom numbers of porcine skin gelatin vary from 90 to 300 g. This product has a gel strength of approximately 300 g. Thus, the average molecular mass would be 50,000-100,000. Please review the Product Information Sheet for further information:
