Alanine Assay Kit provides a sensitive detection method of alanine. In the kit, alanine is converted to pyruvate which is specifically detected leading to proportional color (λ=570nm: 0-10 nmol) or fluorescence (Ex/Em 535/587nm: 0-1 nmol) development. Serum concentration: ~24-76 µg/ml (~3-9 nmol/10 µl).

This kit provides a rapid, simple, sensitive, and reliable assay suitable for research and high throughput assay of Ammonia. In the assay, Ammonia is converted to a product that reacts with the OxiRed probe to generate color (λmax = 570 nm) which can be easily quantified by plate reader. The kit can detect 1 nmol (~20 µM) of ammonia, much more sensitive than measuring NADPH based ammonia assay.

This kit provides a rapid, simple, sensitive, and reliable assay suitable for research and high throughput assay of Ammonia. In this non-enzymatic assay, ammonia is used to form indophenol, a highly colored product easily quantifiable by colorimetry (OD670 nm) using a plate reader. The kit can detect less than 1 nmol (~10 μM) ammonia using either a 96 well or 384 well microwell plate.

FRASC Assay Kit provides a rapid, simple, and sensitive means of detecting ascorbic acid in biological samples such as serum and other body fluids, tissue and cell extracts, growth media and food products. In this assay, Feᶟᶧ is reduced to Fe²ᶧ by any antioxidants present. The ferrous iron is chelated with a colorimetric probe to produce a product with a strong absorbance band which can be monitored between 545-600 nm. The addition of ascorbate oxidase to parallel samples removes any ascorbate present leaving a background value which is subtracted from the total to give ascorbate content. The assay can detect 0.2 to 20 nmol of ascorbic acid in various samples.

Ascorbic Acid Assay Kit provides a rapid, simple, and sensitive means of detecting ascorbic acid in various biological samples. In this assay, our proprietary catalyst oxidizes ascorbic acid to produce a product that interacts with the ascorbic acid probe, generating color and fluorescence. Ascorbic acid can be easily determined by either colorimetric (spectrophotometry at λ = 570 nm) or fluorometric (Ex/Em = 535/587 nm) methods. The assay can detect 0.01-10 nmol of ascorbic acid per assay in various samples.

Calcium Fluorometric Assay kit provides an easy and quantitative method to measure Calcium in various biological fluids. Low concentration of N,N,N’,N’-tetrakis-(2-pyridylmethyl)ethylenediamine (TPEN) is included in the assay and used to pre-treat samples to eliminate interference from other di-valent metals such as Zinc. The assay is based on the ability of our proprietary probe that binds specifically to Calcium cations generating a high fluorescence signal. The fluorescence is directly proportional to the amount of calcium, which can be quantified by measuring the generated fluorescence (Ex/Em= 500/530 nm) using a microplate reader. This assay kit provides an add-and-read, non-radioactive, and high-throughput adaptable assay suitable for Calcium detection. The assay is rapid (less than 10 min) and sensitive (Limit of Detection: <0.1 µM).
