Rabbit anti Human PP2A-alpha Antibody, Polyclonal, could be used for WB, IHC and so on. Application: WB: 1/1000 IHC: 1/100-1/500 Protein Function: PP2A can modulate the activity of phosphorylase B kinase casein kinase 2, mitogen-stimulated S6 kinase, and MAP-2 kinase. Cooperates with SGOL2 to protect centromeric cohesin from separase-mediated cleavage in oocytes specifically during meiosis I (By similarity). Can dephosphorylate SV40 large T antigen and p53/TP53. Dephosphorylates SV40 large T antigen, preferentially on serine residues 120, 123, 677, and perhaps 679. The C subunit was most active, followed by the AC form, which was more active than the ABC form, and activity of all three forms was strongly stimulated by manganese, and to a lesser extent by magnesium. Dephosphorylation by the AC form, but not C or ABC form is inhibited by small T antigen.

PP2A-alpha Antibody (Ab122718) - IHC Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by AEC staining. This data demonstrates the use of PP2A-alpha Antibody (Ab122718) for immunohistochemistry; clinical relevance has not been evaluated. HC = hepatocarcinoma.
PP2A-alpha Antibody (Ab122718) - IF/ICC
IF analysis of PP2A-alpha Antibody (Ab122718) in HeLa cells. The cells were fixed with 4% PFA for 10 minutes, permeabilized with 0.3% Triton X-100 (I743383) for 10 minutes and then blocked with 5% BSA for 1 hour at room temperature. Cells were stained with PP2A-alpha Antibody (Ab122718) at 1/200 dilution in blocking buffer overnight at 4°C, and then incubated with Goat Anti-Rabbit IgG H&L (AF488) (Ab181954) at a dilution of 1/1000 for 1 hour at room temperature in the dark (green). Cells were counterstained with DAPI (blue).

よくある質問
What does ExactAb? mean?
ExactAb? indicates the product has been validated for use in rigorous antibody validation workflows. Validation may include positive/negative control samples, signal-to-noise testing, and protocol-specific QC. Lot-specific test data is published on the Certificate of Analysis where available.
What does Carrier Free mean?
Carrier Free indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.
How should this product be stored?
Store at ?20 °C. Avoid repeated freeze–thaw cycles. Aliquot into single-use volumes before freezing.
How is this product shipped?
This product ships in an insulated container with ice pads. Unpack on arrival and transfer it to the storage condition stated above.
What documentation is provided?
Available product documentation, including Certificates of Analysis (COA), Safety Data Sheets (SDS), and specification sheets, is shown in the product document area. Document availability and access follow the current site policy.
Which species reactivity has this antibody been validated against?
Validated reactivity is listed on the PDP and on each lot's datasheet. We validate against the most commonly tested species for the target (PP2A-alpha Antibody); cross-reactivity in untested species may exist but is not guaranteed. Contact technical support for specific species inquiries.
