Santa Cruz Biotechnology mouse anti pax8

(A) Endogenous PBRM1 was immunoprecipitated (IP) from human embryonic kidney cells (HEK293, left) and RCC cells (ACHN, right), and co-purified proteins were analyzed by LCMS/MS. Shown are identified coactivator (CoA) components and transcription factors. Circle size indicates abundance of protein in the interactome. A minimum Mascot ion score of 25 and peptide rank 1 were used for automatically accepting all peptide MS/MS spectra. The most enriched functional group was “ATPase chromatin remodeling complex” (p value Bonferroni-corrected 1.42 × 10 −27 ). The STRING database system was used to construct the protein-protein interaction network with a parameter STRONG score >0.4. Detection, quantification, Gene Ontology (GO), and STRING data for these and other proteins are in . Heatmap shows quantification versus IP with immunoglobulin G (IgG) isotype control. (B) Heatmap summary of the data shown in (A). (C) Bi-directional IP-western blots in 293T and three RCC cell lines confirmed the interaction between PBRM1 and <t>PAX8.</t> The RCC cell lines used were ACHN, SKRC45, and SKRC29.
