General description
La tripsina es una proteasa de serina que se utiliza generalmente en bioquímica y biología como un reactivo enzimático importante.[1] Este método produce un producto de tripsina muy purificado adecuado para la investigación en proteómica. Grado proteómica ideal para su uso tanto en soluciones como en hidrolizados de tripsina en gel. La tripsina, una proteasa de serina, está presente en el sistema digestivo de varios vertebrados.[2]
Application
La tripsina del páncreas porcino se utiliza para las siguientes aplicaciones:
- Digestión proteica en gel y análisis mediante espectrometría de masas con MALDI-TOF[3]
- Análisis mediante espectrometría de masas de ionización por electrospray (ESI-MS)[4]
- Perfilado del proteoma de superficie de L. plantarum[5]
- Filtración en gel, ultracentrifugación y microscopia electrónica de sombras rotatorias[6]
- Espectrometría de masas[7][8]
Biochem/physiol Actions
La tripsina se utiliza habitualmente en la investigación proteómica para la cartografía de péptidos y el trabajo de secuenciación de proteínas, debido a su escisión muy específica que produce un número limitado de péptidos tripsínicos. Hidroliza los enlaces peptídicos específicamente en el lado carboxilo de los restos de arginina y lisina.[2] La enzima exhibe también actividades esterasa y amidasa.[9] La tripsina actúa como una herramienta de cultivo celular. Se utiliza para hidrolizar proteínas alergénicas y producir leche hipoalergénica en la industria.[1]

How can we digest protein using Product T6567, Trypsin from porcine pancreas?
1 answer-
As per Sigma R and D the information is as follows: In order to efficiently digest a protein with trypsin, it must be denatured and the disulfide bonds modified by reduction and alkylation, or at least reduced. Many intact proteins are highly resistant to digestion with trypsin. If you do not want to reduce and alkylate, you can then just boil the protein with 5 mM DTT or 20 mM 2ME for 10 minutes, and then quickly cool on ice to denature the protein. This may result in a precipitate, but the trypsin will still digest the protein and it will clear within an hour or two. You can also dissolve the protein in 6 M guanidine-HCl or 8 M urea. Reduce and alkylate using the PROT-RA kit or other suitable method. Then they would have to dilute the solution to less than 2 M of either denaturant and then add the trypsin. This is the method that we use routinely in the lab.
