Description: The Lactose Assay Kit measures total lactose in milk based food products or biological samples such as blood or urine. Lactose is cleaved into glucose and galactose. Glucose is then oxidized, yielding hydrogen peroxide and D-gluconic acid. The hydrogen peroxide is detected by a fluorometric probe.

Description: Bilirubin, a byproduct of heme breakdown, can exist conjugated to glucuronic acid (direct) and as unconjugated (indirect). The unconjugated form is found in the blood bound to albumin and is transported to the liver. Bilirubin becomes conjugated to glucuronic acid in the liver, making it more soluble and allowing for excretion into bile. High levels of bilirubin have been correlated with jaundice and Gilbert?s syndrome while low levels have been associated with cardiovascular disease and diabetes mellitus.

Description: Our Pyruvate Assay Kit measures pyruvate in biological samples. First, pyruvate is oxidized by pyruvate oxidase, producing hydrogen peroxide. The hydrogen peroxide is then detected at ex. 530-570 nm/em. 590-600 nm using a specific fluorometric probe. Pyruvate levels in unknown samples are determined based on the provided pyruvate standard curve.

Description: Cell Biolabs? Urea Assay Kit is based on the Berthelot reaction.  Urea is first degraded into ammonia and carbon dioxide, which further reacts with an alkaline developer to produce a blue-green colored product that can be measured with a standard spectrophotometric plate reader at an optical density between 580-630 nm.  Each kit provides sufficient reagents to perform up to 192 assays, including blanks, urea standards and unknown samples.

Description: Our Rac Activation Assays use visible agarose beads to selectively precipitate the active form of Rac1 or Rac2. The precipitated small GTPase is then detected by Western blot using a Rac1- or Rac2-specific antibody included in the kit.

Description: Our Cdc42 Activation Assays use visible agarose beads to selectively precipitate the active form of Cdc42 protein. The precipitated small GTPase is then detected by Western blot using a Cdc42-specific antibody included in the kit.

Description: Our Rho Activation Assays use visible agarose beads to selectively precipitate the active form of RhoA, RhoB or RhoC. The precipitated small GTPase is then detected by Western blot using a RhoA-, RhoB- or RhoC-specific antibody included in the kit.
