Biotin Microtiter Plate Assay


The Biotin Microtiter Plate Assay is a microtiter plate test kit based on a microbiological assay which measures the total free biotin content in serum.  The test kit contains all required reagents, e.g. standard, medium and microtiter plate coated with a specific microorganism, sufficient for 96 determi­nations including standard curves.  An ELISA reader is required for evaluation of the biotin con­tent. The Biotin Assay kit is for research use only and not for use in diagnostic procedures.

Preparation and Storage of Reagents

  • Store test kit / reagents at 2-8°C.
  • Prepare reagents freshly and use immediately after preparation. Discard remaining unused reagents and waste in accordance with country, federal, state, and local regulations.
  • Put unused reagents (standard, controls, medium) in the test kit and store at 2-8°C.
  • Take as many microtiter strips as needed from kit. Store unused strips in the original package bag at 2-8° C to prevent contamination or moisture exposure.
  • No warranty can be given after the expiry date (see label of test package).
  • To run assay more than once, ensure that reagents are stored at conditions stated on the label. Prepare only the appropriate amount necessary for each assay.The kit can be used up to 3 times within the expiry date stated on the label.

Assay Principle

Serum samples are diluted and added into the microtiter plate wells coated with Lacto­bacillus plantarum which metabolizes biotin. The presence of biotin both in standards [STD] and samples gives a biotin-dependent growth response. After incubation at 37°C for 48 h, the growth of Lactobacillus plantarum is measured turbidimetrically at 610 – 630 nm (alternative at 540 – 550 nm) in an ELISA-reader. A dose-response curve of absorbance unit (optical density, OD at 610 nm) vs. concentration is generated using the values obtained from a standard. Biotin present in the patient samples is determined directly from this curve.

Additional Information

Assay Background

In the late 1950s, the discovery of covalently bound biotin with a coenzyme function was reported. Biotin is a growth factor present in minute amounts in every living cell. The fact that humans have a requirement for biotin has been most clearly shown in 2 situations that result in biotin deficiency: 1) prolonged consumption of raw egg whites and 2) parenteral nutrition without biotin supplementation in patients with short-gut syndrome. Biotin plays an indispensable role in numerous naturally occurring carboxylation reactions. The daily biotin requirements for adults lie between 100 and 200 mg. Renewed interest in the role of biotin in human nutrition and therapy stems from the accumulating reports of various biotin-responsive syndromes.
