Product Info

• Predicted Species Reactivity: Human|Mouse|Mus musculus|Rat|Rattus norvegicus
• Application: Enzyme-linked Immunosorbent assay-Sandwich
• ELISA Kit Detection Method: Colorimetric
• ELISA Kit Duration: 3h
• ELISA Kit Principle: The 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 Proliferating Cell Nuclear Antigen (PCNA). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Proliferating Cell Nuclear Antigen (PCNA). 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 Proliferating Cell Nuclear Antigen (PCNA), 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 Proliferating Cell Nuclear Antigen (PCNA) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
• ELISA Kit Range: 0.156-10ng/mL
• ELISA Kit Reproducibility: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Proliferating Cell Nuclear Antigen (PCNA) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Proliferating Cell Nuclear Antigen (PCNA) were tested on 3 different plates, 8 replicates in each plate.

Target Info

• Gene Symbol: Pcna
• Gene Full Name: proliferating cell nuclear antigen
• Alias Symbols: cyclin;Pcna/cyclin;PCNAR;proliferating cell nuclear antigen.
• NCBI Gene Id: 18538|25737
• Protein Name: Proliferating cell nuclear antigen
• Description of Target: Auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase's processibility during elongation of the leading strand. Induces a robust stimulatory effect on the 3'-5' exonuclease and 3'-phosphodiesterase, but not apurinic-apyrimidinic (AP) endonuclease, APEX2 activities. Has to be loaded onto DNA in order to be able to stimulate APEX2. Plays a key role in DNA damage response (DDR) by being conveniently positioned at the replication fork to coordinate DNA replication with DNA repair and DNA damage tolerance pathways. Acts as a loading platform to recruit DDR proteins that allow completion of DNA replication after DNA damage and promote postreplication repair: Monoubiquitinated PCNA leads to recruitment of translesion (TLS) polymerases, while 'Lys-63'-linked polyubiquitination of PCNA is involved in error-free pathway and employs recombination mechanisms to synthesize across the lesion (By similarity).
