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).

Chloride Assay Kit provides a quick, simple method for quantification of Chloride in a variety of biological samples. Blood and urine can be used directly after dilution with water. The assay is based upon the competition of Hg²ᶧ and Fe²ᶧ for TPTZ. The preferred Hg-TPTZ adduct exhibits no color. In the presence of Chloride, Hg²ᶧ forms HgCL2 freeing up TPTZ which then binds the available Fe²ᶧ giving a very intense absorbance with a λmax~ 620nm. The assay is linear in the range 20 to 120 nmol Chloride/well with detection sensitivity ~0.4 mM chloride.

Citrate Assay Kit provides a simple, sensitive and rapid means of quantifying citrate in a variety of samples. In the assay, citrate is converted to pyruvate via oxaloacetate. The pyruvate is quantified by converting a nearly colorless probe to an intensely colored (570 nm) and fluorescent (Ex/Em, 535/587 nm) product. The Citrate Assay Kit can detect 0.1 to 10 nmoles (~2 µM-10 mM) of citrate in a variety of samples.
