Datasheets/ManualsPrintable datasheet for PARN ELISA Kit (Human) (OKCD01246)
Product Info
Predicted Species ReactivityHomo sapiens|Human
ApplicationEnzyme-linked Immunosorbent assay-Sandwich
ELISA Kit Detection MethodColorimetric
ELISA Kit Duration3h
ELISA Kit PrincipleThe test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Poly A Specific Ribonuclease (PARN). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Poly A Specific Ribonuclease (PARN). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Poly A Specific Ribonuclease (PARN), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Poly A Specific Ribonuclease (PARN) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
ELISA Kit Range0.781-50ng/mL
ELISA Kit ReproducibilityIntra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Poly A Specific Ribonuclease (PARN) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Poly A Specific Ribonuclease (PARN) were tested on 3 different plates, 8 replicates in each plate.

Protein NamePoly(A)-specific ribonuclease PARN
Description of Target3'-exoribonuclease that has a preference for poly(A) tails of mRNAs, thereby efficiently degrading poly(A) tails. Exonucleolytic degradation of the poly(A) tail is often the first step in the decay of eukaryotic mRNAs and is also used to silence certain maternal mRNAs translationally during oocyte maturation and early embryonic development. Interacts with both the 3'-end poly(A) tail and the 5'-end cap structure during degradation, the interaction with the cap structure being required for an efficient degradation of poly(A) tails. Involved in nonsense-mediated mRNA decay, a critical process of selective degradation of mRNAs that contain premature stop codons. Also involved in degradation of inherently unstable mRNAs that contain AU-rich elements (AREs) in their 3'-UTR, possibly via its interaction with KHSRP. Probably mediates the removal of poly(A) tails of AREs mRNAs, which constitutes the first step of destabilization.
