SPANX-C Antibody

• Catalog Number: orb344633
• Category: Antibodies
• Description: SPANX-C antibody
• Clonality: Polyclonal
• Species/Host: Rabbit
• Isotype: IgG
• Conjugation: Unconjugated
• Reactivity: Human
• Form/Appearance: Lyophilized
• Concentration: 5.0 mg/mL
• Buffer/Preservatives: 0.01% (w/v) Sodium Azide
• Purity: This Protein A purified antibody is directed against human SPANX-C protein. The product was purified from monospecific antiserum by protein A chromatography followed by exhaustive dialysis against the buffer stated above. A protein-protein BLAST analysis was used to suggest cross reactivity with most SPANX proteins from human, gorilla and chimpanzee. Reactivity against homologues from is not known.
• Immunogen: This Protein A purified antibody was prepared from whole rabbit serum produced by repeated immunizations with full-length recombinant human SPANX-C protein.
• UniProt ID: Q9NY87
• Tested applications: ELISA, IHC, WB
• Dilution range: ELISA: 1:5,000 - 1:20,000, IHC: 1.25-2.5 µg/ml, WB: 1:1,000 - 1:5,000
• Application notes: This protein A purified antibody has been tested for use in ELISA, immunohistochemistry, and by western blot. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 15-20 kDa in size corresponding to SPANX family members by western blotting in the appropriate human tissue. Most human cell lines are SPANX negative.
• Antibody Type: Primary Antibody
• Storage: Store vial at 4° C prior to restoration. For extended storage aliquot contents and freeze at -20° C or below. 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.
• Alternative names: rabbit anti-SPANX-C antibody, Cancer-testis-associ
• Note: For research use only

Biorbyt's affinity purified anti-SPANX-C antibody was used at 2.5 µg/ml to detect signal in a variety of tissues including multi-human, multi-brain and multi-cancer slides. This image shows moderate positive staining of human sperm and spermatids at 60X. Tissue was formalin-fixed and paraffin embedded. The image shows localization of the antibody as the precipitated red signal, with a hematoxylin purple nuclear counterstain.

Western blot using Biorbyt's Protein A purified anti-SPANX-C antibody shows detection of a band at ~17 kDa corresponding to SPANX-C present in a nuclear extract from VWM105 cells (left panel, arrowhead). VWM105 cells are derived from a human melanoma and are positive for SPANX proteins. Lane 2 shows reactivity with a purified recombinant SPANX-C fusion protein. The right panel shows similar reactivity with purified recombinant SPANX-B, SPANX-C and SPANX-N proteins. Proteins were separated by SDS-PAGE, transferred to nitrocellulose, and probed with the primary antibody diluted to 1:1000. IRDye™800 conjugated Gt-a-Rabbit IgG [H&L] MX was used (left).
