Human PR domain zinc finger protein 8 (PRDM8) ELISA Kit

A family of PRDM proteins are similar to histone methyltransferases (HMTases) with SET domain in that they modulate different cellular processes, including transcriptional regulation, through chromatin modifying activities.In vitro HMTase assay and immunoblot analysis revealed that PRDM8 specifically methylates H3K9 of histones which indicates transcriptional repression activity of PRDM8. Direct recruitment of PRDM8 to the promoter mediated transcriptional repression and indicated no involvement of HDAC. Tissue blot analyses identified PRDM8 transcripts from brain and testis in adult mouse. PRDM8 repressed the expression of steroidogenic markers, p450c17c and LHR, which indicates its regulatory role in mouse testis development.

Human PR domain zinc finger protein 8 (PRDM8) ELISA Kit has high sensitivity and excellent specificity for detection of Human PRDM8. No significant cross-reactivity or interference between Human PRDM8 and analogues was observed.

This Human PR domain zinc finger protein 8 (PRDM8) ELISA Kit employs a two-site sandwich ELISA to quantitate PRDM8 in samples. An antibody specific for PRDM8 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPRDM8 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PRDM8 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 PRDM8 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.
