What is Trypsin Sigma?

The molecular weight of Trypsin Sigma is about 24,000, and its isoelectric point is about pH 8.9. The molecular weight of trypsin is close to its zymogen (23,300), its isoelectric point is about pH 10.8, and its optimum pH is 7.6 to 8.0. It is the most stable at pH=3. When the pH is lower than this pH, Trypsin Sigma is volatile, and it is easy to dissolve when pH>5; Ca2+ ion has a stabilizing effect on trypsin.
Trypsin Sigma can catalyze the hydrolysis of proteins, and has a high degree of specificity for the bonds formed by the carboxyl groups of basic amino acids (arginine, lysine) and the amino groups of other amino acids. In addition, it can also catalyze the amide bond or ester bond formed by the basic amino acid and the carboxyl group, and its high specificity is still manifested in the selection of one end of the basic amino acid.
As a type of protease, Trypsin Sigma not just functions as a digestive system enzyme, yet additionally restricts as well as turns on the precursors of various other enzymes such as chymotrypsinogen, carboxypeptidase, as well as phospholipase.
Additionally, it has anti-inflammatory results. It is medically utilized for neighborhood edema, hematoma and abscess caused by empyema, hemothorax, medical swelling, abscess, distressing injury, fistula, etc.

Trypsin Sigma Uses

  1. Trypsin Sigma is utilized for biochemical study, protein framework analysis as well as sequence study, healthy protein digestion as well as decomposition. Diseases such as emphysema and bronchitis.
  2. Trypsin Sigma is utilized for numerous surgical ulcers and edema and parasites brought on by swollen gangrene, terrible azole injury, fistula holes, and so on.
  3. Trypsin Sigma works as a proteolytic enzyme. Inner medication is primarily utilized for empyema, emphysema, bronchitis, bronchial asthma blood clot. However, it may cause unfavorable responses such as chills, fever, headache, chest discomfort, abdominal pain, dyspnea, breakout, angioedema, raised intraocular pressure, and leukopenia, as well as seldom anaphylactic shock. The intramuscular shot website is prone to discomfort and also induration. It can not be made use of for hemorrhaging tooth cavity, severe inflammation, and clients with pulmonary hemorrhage within one week. Usage with care in people with tuberculous empyema and also tracheopleural fistula. It is contraindicated in patients with liver as well as kidney damage, abnormal blood coagulation function as well as bleeding. Before use, include an ideal quantity of sodium chloride shot to liquify. Intramuscular injection: regional injection or spray breathing, the dose depends upon the condition.
  4. Trypsin Sigma is readily available as an enzyme prep work. Generally utilized for toasting, meat tenderization, healthy protein hydrolysis, etc.
  5. Trypsin Sigma has the exact same chemical residential properties as animal-derived trypsin. It can be used as opposed to trypsin, as well as has several benefits, such as no miscellaneous enzyme task, high stability, no self-cleavage, high activity; in operation, no non-specific enzyme bosom pieces as well as self-cleavage fragments show up. It is utilized for particular protein food digestion, healthy protein sequencing, making peptide maps, proteomics research study, trypsin food digestion of peptides on Z-D gel, and so on.

Trypsin Sigma Preparation

1. Trypsin crude production operation:
1. Extraction process:
1.1 For fresh pancreas, use forceps and scissors to remove the fatty connective tissue, etc., mince it in a mincer, and weigh 15Kg;
1.2 Put the minced material in a plastic bucket, soak it with 30L of 0.125mol/L sulfuric acid solution for 24 hours, and stir it once per hour during the soaking period;
1.3 Put the impregnated material into a filter bag for filtration, and then soak the filter residue with 15 L of 0.125mol/L sulfuric acid solution for 1 hour, and then discard the filter residue after filtration;
2. Salt dissolving and salting out process:
2.1 Combine the two dipping liquids with a volume of 44.9L, put them in a plastic bucket, add 242g of solid ammonium sulfate to every 1000ml of the solution to reach 40% saturation, add a total of 10.866Kg of solid ammonium sulfate, and let stand for 12 hours;
2.2 Filter, keep the filtrate, the filtrate volume is 44L, and the solid is discarded;
2.3 Add 205g of solid ammonium sulfate to every 1000ml of clear liquid to reach 70% saturation, share 9.020kg of ammonium sulfate, and let stand for 12 hours;
2.4 Filter, keep the filter cake, weigh 269.2g, and discard the filtrate;
2.5 Dissolve with 807.6ml of water, and then add solid ammonium sulfate to precipitate at nearly 40% and 70% saturation according to steps 2.1, 2.2, 2.3, and 2.4;
2.6 Take 70% saturation precipitate, weigh 178.5g, dissolve it in 267.8ml water, add 89.3ml saturated ammonium sulfate solution, and adjust the pH to 5.00 with 5mol/L sodium hydroxide solution;
2.7 The solution was left to stand in an incubator at 25°C for 48 hours, and a needle-shaped crude chymotrypsin product crystallized out;
