Vitamin H ELISA Kit (Biotin)

Full Name: Vitamin H ELISA Kit (Biotin)
Sample Type: Food
Sensitivity: 0.5 ng/ml


Vitamin H (biotin) belongs to the family of B complex group of vitamins. They function in helping to convert food (for example; carbohydrates, amino acids and fats) into fuel (e.g. glucose) that is used to produce energy. These are water soluble (i.e. the body is unable to store them), however, biotin can be produced by bacteria within the intestines and small amounts can be found in many foods. Some of the common foods include: cooked eggs, sardines, brewer’s yeast, nuts (pecans, almonds, walnuts and peanuts), soybeans, whole grains, banana, mushroom, cauliflower and other legumes (such as blackeye peas and beans).

The following assay is intended for measuring quantitative levels of biotin in food. Many food-processing techniques can destroy biotin, whereas less-processed versions of the same foods are found to contain more biotin. It is also recommended for strengthening nails and hair and is often found to be added to many cosmetic products for skin and hair.


Vitamin H ELISA kit is designed for detecting quantitative concentrations of biotin (vitamin H) in food. This assay has a minimum analytical sensitivity limit of 0.5 ng/ml.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

  • Microtiter Plate: Coated with avidin.
  • Biotin Standards 1-6: Concentration 01, 2.5, 5, 10, 25 ng/ml.
  • Conjugate (Biotin-Alkaline-Phophatase).
  • Substrate Solution (PNPP).
  • Stop Solution (1 M NaOH).

The minimum detection sensitivity level of vitamin H (biotin) using current vitamin H ELISA kit was 0.5 ng/ml. The standard range for this assay is 1.0 – 25.0 ng/ml.


– Sensitivity: 0.5ng/ml (based on the standard curve).
– Recovery: 98% based on spiked samples.
– Intra-Assay Precision: 3%

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
