High purity recombinant Adenylate kinase (Myokinase) (prokaryote) for use in research, biochemical enzyme assays andin vitro diagnostic analysis.

EC 2.7.4.3

Recombinant from a prokaryote. 
In 3.2 M ammonium sulphate.

Specific activity: 1496 U/mg (25^oC, pH 7.6).

Stable at 4^oC for > 2 years.

High purity recombinant Alcohol dehydrogenase (E. coli) for use in research, biochemical enzyme assays and in vitrodiagnostic analysis.

EC 1.1.1.1

Recombinant from E. coli. 
In 3.2 M ammonium sulphate.

Specific activity: ~ 10 U/mg (25^oC, pH 8.5).

Low K_m for ethanol: due to the low K_m of this enzyme, only 3 units are required per assay (TV = 2.54 mL) compared to 177 units of the yeast enzyme.

A simple method for the rapid and reliable measurement of formic acid (formate) in foods, beverages and other materials. Content:25 assays per kit

UV-method for the determination of Formic Acid in foods,
beverages and other materials

Principle:
(formate dehydrogenase)
(1) Formic acid + NAD⁺ → CO₂ + NADH + H⁺

                                         / 220 (auto-analyser)
Method:                            Spectrophotometric at 340 nm
Reaction time:                  ~ 12 min
Detection limit:                 0.0932 mg/L
Application examples: 
Wine, fruit juices, pickles, vinegar, jam, bakery products, honey, fish,
meat and other materials (e.g. biological cultures, samples, etc.)
Method recognition:     
Methods based on this principle have been accepted by MEBAK
