CST, 40405W2, Oct-4A (C30A3) Rabbit Monoclonal Antibody (SignalFlex™ mFluor™ Red 780 Conjugate)

Monoclonal Antibody for studying Oct4A. Highly specific and rigorously validated in-house, Oct-4A (C30A3) Rabbit Monoclonal Antibody (SignalFlex^™ mFluor^™ Red 780 Conjugate) (CST #40405) is ready to ship. Product Usage Information SignalFlex™ conjugates are produced using highly validated Cell Signaling Technology ® primary antibodies and conjugation methods that have been rigorously tested, ensuring high-quality conjugates and lot-to-lot consistency. These conjugates are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. However, they are not tested on specific assays. Optimal dilutions/concentrations should be determined by the end user. When performing flow cytometry, we recommend using an isotype control conjugate at the same concentration as the antibody conjugate. Storage Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze. Specificity / Sensitivity Oct-4A (C30A3) Rabbit mAb (SignalFlex™ mFluor™ Red 780 Conjugate) detects endogenous levels of total Oct-4A protein. Based on high sequence homology, this antibody may also detect OCT4-PG1. Species Reactivity: Human, Mouse Source / Purification Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human Oct-4A. The epitope has been mapped to residues surrounding Gly52. Background Oct-4 (POU5F1) is a transcription factor highly expressed in undifferentiated embryonic stem cells and embryonic germ cells (1). A network of key factors that includes Oct-4, Nanog, and Sox2 is necessary for the maintenance of pluripotent potential, and downregulation of Oct-4 has been shown to trigger cell differentiation (2,3). Research studies have demonstrated that Oct-4 is a useful germ cell tumor marker (4). Oct-4 exists as two splice variants, Oct-4A and Oct-4B (5). Recent studies have suggested that the Oct-4A isoform has the ability to confer and sustain pluripotency, while Oct-4B may exist in some somatic, non-pluripotent cells (6,7).
