特徴

• Gelatin is a heterogeneous mixture of water-soluble proteins of high average molecular weights, present in collagen.
• The proteins are extracted by boiling skin, tendons, ligaments, bones, etc.
• in water.
• Type A gelatin is derived from acid-cured tissue and Type B gelatin is derived from lime-cured tissue.
• The charge on a gelatin molecule and its isoelectric point are primarily due to the carboxyl amino and guanidino groups on the side chains.
• Type A gelatin has 78-80 millimoles of free carboxyl groups per 100 g of protein and a pI of 7.0-9.0; type B has 100-115 millimoles of free carboxyl groups per 100 g of protein and a pI of 4.7-5.2.
• The pH of a 1.5% solution at 25 °C is 3.8-5.5 for Type A and 5.0-7.5 for Type B.
• soluble in glycerol and acetic acid, and more 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.
• Applications using gelatin include coating cell culture plates to improve cell attachment for a variety of cell types, addition to PCR to help stabilize Taq DNA polymerase, and use as a blocking reagent in Western blotting, ELISA, and immunohistochemistry.
• In bacteriology, gelatin can be used as a component of culture media for species differentiation.
• Additionally, as a biocompatible polymer, gelatin has been used as a delivery vehicle for the release of bioactive molecules and in the generation of scaffolds for tissue engineering applications.
• Industrial applications include the use of gelatin as a stabilizer, thickener, and texturizer in foods and in the manufacture of rubber substitutes, adhesives, cements, lithographic and printing inks, plastic compounds, artificial silk, photographic plates and films, matches, and light filters for mercury lamps.
• In the pharmaceutical industry, gelatin is used as a suspending agent, encapsulating agent, and tablet binder; and in veterinary applications it is used as a plasma expander and hemostatic sponge.
• Gelatin proteins are also used as additives in purified, recombinant proteins and antibodies.
• Animals or humans exposed to gelatins may invoke antibody response.
• Often the gelatin must be removed prior to such applications.
• Antibodies to gelatins were produced to detect the presence of gelatins in biological samples and or to verify their removal during bioprocess development.
• Many people wish to avoid taking animal derived gelatin due to allergy and for religious or ethical reasons.
• The antibodies to gelatins can be used to detect the presence of gelatin.
• Applications:Suitable for use in ELISA.
• Other applications have not been tested.
• Recommended Dilution:ELISA: 1:1000Optimal dilutions to be determined by researcher.
• Storage and Stability:May be stored at 4°C.
• For long-term storage, aliquot and store at 4°C.
• Do not freeze.
• Aliquots are stable for at least 12 months.
• For maximum recovery of product, centrifuge the original vial prior to removing the cap.
• Further dilutions can be made in assay buffer.
