-
Immunogen: RPA from Saccharomyces cerevisiae consisting of three subunits RFA1 (70 kDa), RFA2 (30 kDa) and RFA3 (14 kDa); overexpressed in E.coli and purified by chromatography; no affinity tags were added to any of three subunits
Host: Rabbit Clonality: Polyclonal Purity: Serum Format: Lyophilized Quantity: 50 µl Reconstitution: For reconstitution add 50 µl of sterile water Storage: Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube. Tested applications: Immunoprecipitation (IP), Chromatin Immunoprecipitation (ChIP), Western blot (WB) Recommended dilution: ChIP, 1 : 20 000 (WB) Expected | apparent MW: 70 + 30 + 14 kDa

-
TCA precipitated protein extracts from a wild type yeast strain (S. cerevisiae) were separated on 10% gel and transferred to a PVDF membrane. Antibody was used in different dilutions: 1: 5000 (1); 1: 10 000 (2); 1: 20 000 (3);
Besides the bands for RFA1 and RFA2 an unspecific band was detected at ~150 kDa.

Open PublicationSILAC-based quantification of changes in chromatin association in cells lacking Rrm3.(A) Equal numbers of light-labeled (wildtype) and heavy-labeled (rrm3?) cells were mixed, nuclei isolated, and the chromatin fraction extracted and analyzed by tandem mass spectrometry using a hybrid linear ion trap-Orbitrap instrument. (B) Subcellular fractionation was verified by following the distribution of proteins in cytoplasmic (Cyto), nucleoplasm (NP), and chromatin (Ch) fractions during the enrichment procedure by Western blotting. Successful chromatin fractionation is indicated by the enrichment of histone H3 and Rfa and the absence of Adh1. Chromatin fractions were analyzed from three biological replicates in (C) the absence of hydroxyurea and (D) in the presence of hydroxyurea. (E) Merger of peptide quantification in the absence and presence of hydroxyurea.

Additional information (application): Antibody was also successfully used in ChIP application Holstein et al. (2014).
Load of 1 ng of the protein will allow to visualize two subunits of RPA, while load of 5 ng will allow to visualize all three subunits in Western blot technique. - Background
-
Background: Saccharomyces cerevisiaereplication protein A (RPA), also known as replication factor A (RFA) is a single-stranded DNA-binding protein that is required for multiple processes in eukaryotic DNA metabolism. Those processes include DNA replication, DNA repair, and recombination. Homologues to RPA have been identified in all eukaryotic organisms examined. RPA is heterotrimeric protein composed of subunits of approximately 70, 30, and 14 kDa. Members of this family bind nonspecifically to single-stranded DNA and interact with and/or modify the activities of multiple proteins. Alternative names: Replication protein A 69 kDa DNA-binding subunit, Single-stranded DNA-binding protein, DNA-binding protein BUF2, replication protein A 36 kDa subunit, DNA-binding protein BUF1 antibody
