Human Prohibitin (PHB) ELISA Kit

Prohibitin is a protein which in humans is encoded by the PHB gene. The Phb gene has also been described in animals, fungi, plants and unicellular eukaryotes. Prohibitins are divided in two classes, termed Type-I and Type-II prohibitins, based on their similarity to yeast PHB1 or PHB2, respectively. Each organism has at least one copy of each type of prohibitin gene.Prohibitins are evolutionarily conserved genes that are ubiquitously expressed. The human prohibitin gene, located on the BRCA1 chromosome region 17q21, was originally thought to be a negative regulator of cell proliferation and a tumor suppressor. This anti-proliferative activity was later attributed to the 3' UTR of the PHB gene, and not to the actual protein.

Human Prohibitin (PHB) ELISA Kit has high sensitivity and excellent specificity for detection of Human PHB. No significant cross-reactivity or interference between Human PHB and analogues was observed.

This Human Prohibitin (PHB) ELISA Kit employs a two-site sandwich ELISA to quantitate PHB in samples. An antibody specific for PHB has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPHB present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PHB is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PHB bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
