Description
The FastScan™ PCNA ELISA Kit is a sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of PCNA. To perform the assay, sample is incubated with a capture antibody conjugated with a proprietary tag and a second detection antibody linked to HRP, forming a sandwich with PCNA in solution. This entire complex is immobilized to the plate via an anti-tag antibody. The wells are then washed to remove unbound material. TMB is then added. The magnitude of observed signal is proportional to the quantity of PCNA.
*Antibodies in this kit are custom formulations specific to kit.
IMPORTANT: This FastScan™ ELISA Kit requires 4 washes at Step 6 of the protocol.
Specificity/Sensitivity
Background
Proliferating cell nuclear antigen (PCNA) is a member of the DNA sliding clamp family of proteins that assist in DNA replication (1). Crystal structure data suggests that a PCNA homotrimer ring can encircle and slide along the DNA double helix (2). Multiple proteins involved in DNA replication, DNA repair, and cell cycle control bind to PCNA rather than directly associating with DNA, thus facilitating fast processing of DNA (reviewed in 3). PCNA protein expression is a well-accepted marker of proliferation.
