PCNA Antibody (600-401-887) in WB
Western blot using Rocklands Affinity Purified anti-Alga PCNA antibody shows detection of a predominant band at ~29 kDa corresponding to PCNA (arrowhead lane 2). Peptide competition effectively eliminates specific band reactivity (lane 1). For peptide competition, the antibody was pre-incubated with 100 µg (excess) of the peptide for 2h at 37° C followed by overnight incubation at 4 °C with 100 µg (excess) of the peptide, followed by a brief centrifugation and then reaction with the membrane. Each lane contains a lysate from 105 cells from... View More

Product Specific Information
Store vial at -20° C prior to opening. Aliquot contents and freeze at -20° C or below for extended storage. Avoid cycles of freezing and thawing.

This affinity purified antibody is directed against algal PCNA. A BLAST analysis was used to suggest that this antibody would react with PCNA from the following alga sources: Prorocentrum minimum, Tetraselmis chui, Pleurochrysis carterae and Isochrysis galbana. Expect partial reactivity with PCNA from other alga sources as well as carrot, tobacco, peas, soybean and rice based on partial protein sequence homology. Species that have been tested but yielded no positive results are Pfiesteria piscicida, Emiliania huxleyi, Akashiwo sanguinea, Rhodomonas sp., Karlodinium micrum, and Skletonema costatum. Reactivity with PCNA from other sources has not been determined.
Target Information
PCNA (polymerase delta auxiliary protein) is essential for DNA replication and is involved in DNA excision and mismatch repair pathways. PCNA binds to the CDK inhibitor p21, the structure-specific endonucleases Fen1 and XPG, and DNA cytosine 5-methyltransferase (MCMT). PCNA is a potentially useful marker of cells with proliferative potential and for identifying the proliferation status of tumor tissue (i.e. relevant to prognosis). PCNA is a marker for cells in early G1 phase and S phase of the cell cycle. PCNA is found in the nucleus and is a cofactor of DNA polymerase delta, and acts as a homotrimer and helps increase the processing of leading strand synthesis during DNA replication. In response to DNA damage, PCNA is ubiquitinated and is involved in the RAD6-dependent DNA repair pathway. Two transcript variants encoding the same protein have been found for PCNA. Pseudogenes of PCNA have been described on chromosome 4 and on the X chromosome.
