Cell Biolabs Inc Beta-Hexosaminidase Assay Kit, 100 assays
Hexosaminidase is an enzyme that hydrolyzes terminal N-acetyl-D-hexosamine residues from N-acetyl-ß-D-hexosaminidines. The enzyme is typically found as a dimer of the alpha and beta subunits. Cell Biolabs' Beta Hexosaminidase Assay Kit quantifies the activity of the beta subunit in a convenient 96-well microplate format. Each kit provides sufficient reagents for 100 assays including standards and unknown samples.
Aat Bioquest Amplite™ Fluorimetric HDAC Activity Assay Kit *Green Fluorescence*
Histone deacetylases (HDAC) are a class of enzymes that remove acetyl groups from a ε-N-acetyl lysine amino acid on a histone.
Bioassay Systems QuantiFluo™ ALP Reagent. Stabilized 4-methylumbelliferyl phosphate (MUP) liquid substrate reagent for detecting alkaline phosphatase ALP, e.g. in ELISA.
Stabilized 4-methylumbelliferyl phosphate (MUP) liquid substrate reagent for detecting alkaline phosphatase ALP, e.g. in ELISA. This single reagent produces a highly fluorescent product (360/450 nm) when dephosphorylated by ALP. The fluorescent product can also be visualized under a UV light. Key Features: Stable single reagent. Highly sensitive fluorescence detection. Can be visualized under a UV light. Method: FL360/450nm. Samples: Biological. Species: All. Procedure: Assay takes 30 min. Kit size: 600 tests.
QuantiFluo™ ALP Reagent is a stable 4-methylumbelliferyl phosphate (MUP) liquid substrate reagent formulated for detecting alkaline phosphatase ALP, e.g. in ELISA.

TRIBIOSCIENCE INC LDH Lactate Dehydrogenase Colorimetric Assay Kit, 500 Tests
LDH Colorimetric Assay Kit provides the easiest and most accurate approach to measure LDH activity. The generated signal at OD 460 nm is proportional to the LDH released from the lysed cells.
AnaSpec SENSOLYTE 520 TEV ACTIVITY KIT
SensoLyte 520 TEV Activity Assay Kit *Fluorimetric*, (1 kit) Tobacco Etch Virus (TEV) proteinase is widely used to remove fusion tags from recombinant proteins. It recognizes specific sequence Glu-Asn-Leu-Tyr-Phe-Gln-Gly and cleaves between Glutamine and Glycine residues. TEV protease is active even at 4 Deg.C, making it the protease of choice for fusion proteins or tags removal. The SensoLyte TEV Protease Assay Kit uses TEV specific Glu-Asn-Leu-Tyr-Phe-Gln-Gly substrate labeled with 5-FAM dye and QXL 520 quencher. Proteolytic cleavage of this quenched 5-FAM-QXL 520 conjugate yields a brightly green fluorescence, which can be continuously monitored at Ex/Em= 490/520 nm. Increase in fluorescence intensity is directly proportional to the TEV protease quantity/activity.
