Biochain Institute Inc Peroxide Assay Kit, 250 Assays/PK
BioChain's peroxide assay kit is a simple, direct and automation-ready assay for measuring peroxide concentration in biological samples without any pretreatment. The improved method utilizes the chromogenic Fe3+-xylenol orange reaction, in which a purple complex is formed when Fe2+ provided in the reagent is oxidized to Fe3+ by peroxides present in the sample. The intensity of the color, measured at 540-610nm, is an accurate measure of the peroxide level in the sample. The optimized formulation substantially reduces interference by substances in the raw samples.
Biochain Institute Inc Chloride Assay Kit, 500 assays/PK
BioChain's chloride assay kit is a simple, direct and automation-ready assay for measuring chloride concentration in biological samples without pretreatment. The improved Fried method utilizes mercuric 2,4,6-tripyridyl-s-triazine, which forms a colored complex specifically with chloride. The intensity of the color is directly proportional to the chloride concentration in the sample. The optimized formulation substantially reduces interference by substances in the raw samples.

Cell Biolabs Inc Total Bile Acid Assay Kit (Colorimetric), 100 assays
Bile acids are produced from the breakdown of cholesterol in the liver, and bile acid levels in circulation can help identify certain liver diseases. Cell Biolabs' Total Bile Acid Assay Kit is a 96-well plate-based method to measure total bile acid content in a standard 96-well colorimetric plate reader. The assay uses an enzymatic reaction in which bile acids are incubated in the presence of thio-NAD+. The kit can detect bile acid concentrations as low as 0.78 µM in serum, plasma, and cell or tissue lysates. Each kit provides sufficient reagents for 100 assays including standards and unknown samples.
Biochain Institute Inc Phosphate Assay Kit, 500 Assays/PK
BioChain's phosphate assay kit is a simple, direct and automation-ready assay for measuring phosphate concentration in biological and environmental samples without pretreatment. The improved Malachite Green method utilizes the malachite green dye and molybdate, which forms a stable colored complex specifically with inorganic phosphate. The intensity of the color is directly proportional to the phosphate concentration in the sample. The optimized formulation substantially reduces interference by substances in the raw samples.
Biochain Institute Inc Calcium Assay Kit, 500 assays/PK
BioChain's calcium assay kit is a simple, direct and automation-ready assay for measuring calcium concentration in biological samples without pretreatment. A phenolsulphonephthalein dye in the kit forms a very stable blue colored complex specifically with free calcium. The intensity of the color is directly proportional to the calcium concentration in the sample. The optimized formulation minimizes any interference by substances such as magnesium, lipid, protein and bilirubin.
Biochain Institute Inc Creatinine Assay Kit, 500 Assays/PK
BioChain's creatinine concentration assay kit is a simple, direct and automation-ready assay for measuring creatinine in biological samples without pretreatment. The improved Jaffe method utilizes picrate that forms a red colored complex specifically with creatinine. The intensity of the color is directly proportional to the creatinine concentration in the sample. The optimized formulation substantially reduces interference by substances in the raw samples.
