Description: Alkaline Phosphatase (AP) is a widely used marker for both mouse and human embryonic stem cells (ES) and embryonic germ cells (EG). Our StemTAG Alkaline Phosphatase kits provide an efficient system for monitoring cell differentiation or undifferentiation using the AP marker. The StemTAG Alkaline Phosphatase Activity Assay Combo Kits provide reagents for monitoring alkaline phosphatase activity via immunocytochemistry staining as well as in a 96-well plate with either colorimetric or fluorescence detection.

Description: Our Starch Assay Kit (Colorimetric) measures starch in food samples. First, starch is broken down into glucose monomers by amyloglucosidase. Glucose is then oxidized by glucose oxidase, producing D-gluconic acid and hydrogen peroxide. The hydrogen peroxide reacts specifically with the kit?s Colorimetric Probe and is detected with a spectrophotometric plate reader at 540-570nm. Starch levels in unknown samples are determined based on the provided starch standard curve.

Description: Our Lactate Assay Kit measures L-lactate in biological samples. Lactate is first oxidized by lactate oxidase, yielding pyruvate and hydrogen peroxide. The hydrogen peroxide released from this reaction is specifically detected by either a colorimetric or fluorometric probe in a 1:1 ratio. Lactate levels in unknown samples are determined based on a lactate standard curve.

Description: Cell Biolabs? Choline Assay Kits are simple assays that measure the amount of choline present in a variety of sample types in a convenient 96-well microtiter plate format.  Each kit provides sufficient reagents to perform up to 96 assays, including blanks, acetylcholine standards and samples.  Sample choline concentrations are determined by comparison with a known choline standard and measured on a colorimetric plate reader.

Description: Cell Biolabs? Alcohol Assay Kits measure primary alcohols by an enzymatic, oxidation reaction, producing hydrogen peroxide which reacts with the kit?s probe. These assay kits come in either colorimetric or fluorometric. The colorimetric assay has a detection sensitivity limit of ~30 µM (0.0001 % w/v) and the fluorometric has a detection sensitivity limit of ~15 µM (0.00007 % w/v). They can detect various primary alcohols and are not ethanol specific.

Description: The Glucose Assay Kit (Colorimetric) measures total glucose present in food or biological samples. Glucose Oxidase first oxidizes glucose, generating hydrogen peroxide that is detected by a colorimetric probe.
