Detergent Assay Kit |BioAssay Systems- enzymes detergents intensity test kit ,BioAssay Systems' detergent assay kit is designed to measure detergent directly without any pretreatment. Above the critical micellar concentration, detergent forms micelle in solution that trap the colorimetric dye. The intensity of the color is directly proportional to the detergent …Lipase Assay Kit - AbnovaThe Lipase Assay Kit is based on an improved dimercaptopropanol tributyrate (BALB) method, in which SH groups formed from lipase cleavage of BALB react with 5,5’-dithiobis(2-nitrobenzoic acid) (DTNB) to form a yellow colored product. The color intensity, measured at 412 nm, is proportionate to the enzyme activity in the sample.



ELISA technical guide and protocols

Two enzymes are commonly used in ELISA applications. Alkaline Phosphatase (AP) is a large enzyme used in a minority of assays. Its size (140 KDa) makes it difficult to conjugate more than one or two molecules of the enzyme to each molecule of an antibody or avidin, and this limits the amount of signal that can be generated.

Spectrophotometric Enzyme Assays - Creative Enzymes

The spectrophotometric assay is a classic enzyme test and still remains as the most widely used assay for the low cost and robust reproducibility. During a spectrophotometric assay, the operator follows the course of an enzyme reaction by measuring the changes in the intensity of the light absorbed or scattered by the reaction solution.

Enzymes in Laundry Detergents - UMD

Introduction In today's laundry detergents, enzymes such as proteases and amylases are some of the active ingredients. In the U.S., about 50% of liquid detergents, 25% of powder detergents, and almost all powdered bleach additives now contain enzymes to help break down stains that are otherwise hard to remove with conventional surfactants alone.
