QuantiChrom™ Zinc Assay Kit

Overview

For quantitative determination of zinc ion Zn 2+ and evaluation of drug effects on zinc metabolism. The assay uses OD425nm for signal readout. Compatible sample input includes Serum, plasma, urine, saliva, food, beverage, and environment. Typical stated assay timing is 30 min.

Key elements and design rationale

• Readout format: OD425nm supports plate-based signal acquisition and consistent comparison across matched samples.
• Sample compatibility: The stated sample scope includes Serum, plasma, urine, saliva, food, beverage, and environment, which is useful when aligning matrix type with calibration and control design.
• Analytical range context: The supplied specifications include a stated detection limit of 0.78 µg/dL (0.12 µM) for interpreting low-signal samples.
• Feature emphasis: Sensitive and accurate. Uses 50 µL samples. Linear detection range 0.12 µM (0.78 µg/dL) to 10 µM (65 µg/dL) zinc in 96-well assay format.

Additional feature notes highlight Simple and high-throughput. The procedure involves the addition of a single working reagent and incubation for 30 min. Can be readily automated as a high-throughput assay for thousands of samples per day; Improved reagent stability and versatility. The optimized formulation has greatly enhanced the reagent and signal stability. Cuvette or 96-well plate assay formats are possible. Available format information for this listing includes 250 Tests.

Biological background

This product is centered on measurement of zinc within the matrices described for the assay. In practice, datasets from this type of format are typically interpreted by comparing relative signal, activity, or abundance across matched control and experimental groups rather than relying on a single value in isolation. Careful alignment of sample matrix, incubation window, and calibration strategy is important when comparing results across plates, operators, or study days.

More details

Zinc is an essential trace element and plays many key roles in metabolism. It is required for the activity of more than 300 enzymes, the structure of many proteins, and the control of genetic expression. Zinc status affects basic processes of cell division, growth, differentiation, development, performance, and aging through its requirement for synthesis and repair of DNA, RNA, and protein. The common causes of zinc deficiency are low dietary intakes and low bioavailability. Clinical signs of zinc deficiency include acrodermatitis, low immunity, diarrhea, poor healing, stunting, hypogonadism, fetal growth failure, teratology, and abortion. Zinc deficiency has now been recognized to be associated with many diseases such as malabsorption syndrome, chronic liver disease, chronic renal disease, sickle cell disease, diabetes, malignancy, and other chronic illnesses. Simple, direct, and automation-ready procedures for measuring zinc concentration in biological samples are highly desirable in Research and Drug Discovery. BioAssay Systems zinc assay kit is designed to measure zinc directly in biological samples without any pretreatment. The present method utilizes a chromogen that forms a colored complex specifically with zinc. The intensity of the color, measured at 425 nm, is directly proportional to the zinc concentration in the sample.

Research relevance and current trends

• Plate-based quantification and side-by-side group comparison remain central use cases for this assay format.
• The product notes emphasize multi-sample throughput, making it relevant for screening-oriented and larger batch comparison studies.
• The description supports intervention-focused study designs in which researchers compare baseline and perturbed conditions.

Common research applications

• Quantify zinc in serum, plasma, urine by OD425 nm readout.
• Compare treatment or phenotype groups using matched serum, plasma, urine handling.
• Monitor time-course or pre/post changes in serum, plasma, urine across study conditions.

Interpretation is usually strongest when signal changes are assessed alongside matrix-matched controls, replicate agreement, and the assay's stated analytical window.

Notes for experimental interpretation

• Matrix composition, background signal, and sample handling can influence apparent response; compare like-with-like whenever possible.
• Use appropriate blanks, controls, and replicate wells to distinguish biological differences from plate, reagent, or handling variability.
