General Notes
This product (Catalog No. DPABH-14440) is a rabbit-derived polyclonal antibody raised against human PREX1, targeting the amino acid region 700–900 of the protein. It has been affinity purified by Protein A. Phosphatidylinositol 3,4,5-trisphosphate-dependent Rac exchanger 1 protein (PREX1) is a guanine nucleotide exchange factor (GEF) that specifically activates Rac GTPases, particularly Rac1 (PMID: 16243035). PREX1 is activated downstream of G protein-coupled receptors (GPCRs) and receptor tyrosine kinases (RTKs), such as ErbB receptors, and is involved in PI3K/AKT and MAPK signaling pathways (PMID: 28710285; 27358402). It contributes to glucose uptake in adipocytes and promotes tumor cell proliferation, migration, and metastasis in various cancers, including breast, prostate, and melanoma (PMID: 22109529).
DPABH-14440 is suitable for use in Western blot (WB) (1:1,000–1:8,000), IF/ICC (1:200–1:800) applications.
DPABH-14440 is supplied as a liquid formulation in PBS with 0.02% sodium azide and 50% glycerol, pH 7.3. For long-term storage, keep at −20 °C. For short-term use, store at 2–8 °C. Avoid repeated freeze–thaw cycles to maintain antibody integrity and performance.
