Application

This product designed to be used during the subculture of keratinocytes contains Kunitz-type soybean trypsin inhibitor (SBTI) which inhibits the catalytic activity of serine proteases such as trypsin and tryptase. It is used in cell culture to stop the action of trypsin which is used to release cells from substratum during passaging. It may be also useful in other anti-serine protease studies.
Used to neutralize the effects of trypsin/EDTA solution.

Physical form

Solution in 98.7% DPBS and 1.3% Soybean Trypsin Inhibitor.

Reconstitution

Use at a minimum volume ratio of 1:1 TID:trypsin/EDTA.

In vitro expansion is an invaluable method to obtain keratinocytes in amounts necessary for effective transplantation therapies. In vitro cell culturing provokes questions concerning potential epigenetic alterations occurring in expanded cells in the context of usefulness for transplantation and safety.

Serum proteins [molecular weight (MW) > 10,000] are essential for increased insulin-stimulated glucose transport after in vitro muscle contractions. We investigated the role of the kallikrein-kininogen system, including bradykinin, which is derived from kallikrein (MW > 10,000)-catalyzed degradation of serum

A trypsin inhibitor with a Km of 5 x 10(-5) M has been isolated from kohlrabi (Brassica napus var. rapifera). Subtilisin DY is inhibited only weakly and chymotrypsin not at all. The inhibitor is closely related to napin as determined

Protocols

Trypsin Inhibitors

Natural trypsin Inhibitors also known as serine protease inhibitors (serpins) are the largest and most diverse family of protease inhibitors. Serpins control the activation and catabolism of proteins by the inhibition of serine proteases in vivo.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
