Background

Alpha-chymotrypsin, also known as alpha-chymotrypsin, is a serine protease that hydrolyzes the carboxy-terminal peptide bonds of tyrosine, tryptophan, and phenylalanine. Ca2+ is an activator and stabilizer of α-chymotrypsin, and the enzyme is supported by diisopropyl fluorophosphate (DFP), toluenesulfonyl fluoride (PMSF), n-p-toluenesulfonyl-l-phenylalanine chloromethyl ketone (TPCK), chymotrypsin inhibitors, aprotinin, α1-antitrypsin, α2-macroglobulin, and α-2-antitrypsin. Cu2+ and Hg2+ were inhibited by 10mM.
The recombinant human α-chymotrypsin produced by our company was expressed by Pichia pastoris and obtained by multi-step purification without contamination by other proteases.

Unit Definition

At pH 7.8 and 25°C, the amount of enzyme that hydrolyzes 1.0 μmol BTEE per minute is defined as 1 U.

Great Functionality a bit light weight tho!
Color: Black
It’s def functional. It looks nice and is not an eye sore. Def will be easy to maintain for cleaning of dust. HOWEVER, four stars simply cause it is a bit top heavy. I will have to find a solution to weight it down so it’s not so top heavy. Possibly in the future they might design a simple one like this with a simple one pound weight across the bottom. Outside of that tiny little issue…a pretty solid simple compact remote holder that functions. Need I say it is Not an eye sore sitting on th coffee table. That was also a winner n my book.

Minimalist Must-Have.
Color: Black, Color: Black
I recently purchased this faux leather remote control holder, and I couldn’t be more impressed. The design is sleek and minimalist, making it a perfect addition to any modern living room. Its elegant finish gives the impression of genuine leather, yet it comes at an excellent price point that makes it accessible without sacrificing style. The craftsmanship is solid, with clean stitching and a sturdy structure that keeps remotes neatly organized. It’s not only functional but also adds a touch of sophistication to the space. For anyone looking to declutter their coffee table while maintaining a refined aesthetic, this product is a fantastic choice. Overall, it combines practicality, elegance, and affordability in a way that’s hard to beat. Highly recommended!
