APC1 (phospho-S355) antibody

• Catalog Number: orb345494
• Category: Antibodies
• Description: APC1 (phospho-S355) antibody
• Species/Host: Rabbit
• Clonality: Polyclonal
• Tested applications: ELISA, IP, WB
• Reactivity: Human
• Isotype: IgG
• Immunogen: This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an internal region near amino acids 350-375 of Human Apc1 protein.
• Concentration: 1.0 mg/mL
• Dilution range: ELISA: 1:10,000 - 1:35,000, IP: 1:100, WB: 1:200 - 1:2,000
• Form/Appearance: Liquid (sterile filtered)
• Purity: This product is an affinity purified antibody produced by immunoaffinity chromatography using phospho peptide coupled to agarose beads followed by solid phase adsorption(s) against non-phospho peptide and non-specific peptide to remove any unwanted reactivities. This antibody is specific for phosphorylated human APC1 protein at the pS355 residue. A BLAST analysis was used to suggest reactivity with this protein from human, mouse, dog, rat, and bovine based on 100% homology for the immunogen sequence. Cross reactivity with APC1 protein from chimpanzee and chicken is expected as the sequence of the immunogen only varies by one amino acid in from these sources (89% homology). Cross reactivity with APC1 homologues from other sources has not been determined. Minimal reactivity is expected with the non-phosphorylated form of the protein.
• Conjugation: Unconjugated
• UniProt ID: Q9H1A4
• NCBI: 12056971
• Storage: Store vial at -20° C prior to opening. Aliquot contents and freeze at -20° C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.
• Buffer/Preservatives: 0.01% (w/v) Sodium Azide
• Alternative names: rabbit anti-APC1 pS355 Antibody, Anaphase-promotin
• Note: For research use only
• Application notes: This affinity purified antibody has been tested for use in ELISA and western blot. Specific conditions for reactivity should be optimized by the end user. Expect a band ~ 215 kDa in size corresponding to APC1 by western blotting in the appropriate cell lysate or extract.
• Expiration Date: 12 months from date of receipt.

Western blot using Biorbyt's Affinity Purified anti-APC1 pS355 antibody shows detection of a band ~215 kDa corresponding to phosphorylated human APC1 (arrowhead). Lane 1 shows lysate from asynchronous cells. Lane 2 shows lysate from cells treated with thymidine to synchronize cells at the G1/S boundary. Lane 3 shows lysate from cells treated with nocodazole to synchronize cells at the M phase. Phosphorylated APC1 is mostly present only in cell preparations arrested at cell division. Each lane contains approximately 30 µg of HeLa S3 whole cell lysates separated by 12.5% SDS-PAGE followed by transfer to nitrocellulose. After blocking with 5% non-fat dry milk in TTBS, the membrane was probed with the primary antibody diluted to 1:500 for 1 h at room temperature followed by washes and reaction with a 1:5000 dilution of HRP Gt-a-Rabbit IgG [H&L] MX (orb347654) for 45 min at room temperature. ECL reagent was used for detection. Other detection systems will yield similar results.
