Human 28S ribosomal protein S27, mitochondrial (MRPS27) ELISA Kit

Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. MRPS27 encodes a 28S subunit protein, mitochondrial ribosomal protein S27, that may be a functional partner of the death associated protein 3 (DAP3) . Alternative splicing results in multiple transcript variants encoding different isoforms.

Human 28S ribosomal protein S27, mitochondrial (MRPS27) ELISA Kit has high sensitivity and excellent specificity for detection of Human MRPS27. No significant cross-reactivity or interference between Human MRPS27 and analogues was observed.

This Human 28S ribosomal protein S27, mitochondrial (MRPS27) ELISA Kit employs a two-site sandwich ELISA to quantitate MRPS27 in samples. An antibody specific for MRPS27 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyMRPS27 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for MRPS27 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 MRPS27 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.
