Recombinant Trypsin
Description
Recombinant Porcine Trypsin is a genetically engineered protein expressed in E.coli and purified
by high pressure liquid chromatography. There are no contaminating enzyme activities such as carboxypeptidase A and chymotrypsin. No protease inhibitors such as PMSF are contained in the preparation.
Calculation
BAEE Units/ml enzyme = | (ΔA253nm/min Test - ΔA253nm/min Blank)(df) |
(0.001) (0.20) |
df = Dilution factor
0.001 = The change in A253nm/minute per unit of Trypsin at pH 7.6 at 25 °C in a 3.2 ml reaction
mix 0.20 = Volume (in milliliters) of enzyme used
Units/mg solid= | units/ml enzyme |
mg solid/ml enzyme |
Notes
1.This assay procedure is not to be used to assay immobilized trypsins
2.For the USP/NF procedure refer to the USP monograph

Advantages
Animal origin free: The use of recombinant Porcine Trypsin eliminates the risk of virus presence,
and other potential adventitious agents found in animal-derived trypsin. YaxinBio Recombinant
Porcine Trypsin belongs to the AOF level 3.
Stablility: A sterile recombinant trypsin lyophilized powder eliminates the contamination risks and decreases the chance of activity loss in the process of transport and storage.
High purity:
1) Recombinant porcine trypsin provides increased specific activity and eliminates contaminating proteases activities found in extracted enzymes.
2) No other contaminating proteases such as chymotrypsin or carboxypeptidase A.
Recommend Usage
Prepare 1-10mg/ml recombinant trypsin with 1mM HCl.The ratio to aimed protein is 1:50 to 1:1000 (w/w).The optimum pH is pH7.0-9.0.
Storage Instructions
Recombinant trypsin lyophilized should be stored under 2℃-8℃ in sealed container. It is stable
within 24 months.After dissolved, it should be stored under -20℃. It is stable within 24 months and
above 90% activity remained after 10 times repeated freezing and thawing.
