SFRP1 antibody

• Catalog Number: orb345444
• Category: Antibodies
• Description: SFRP1 antibody
• Species/Host: Rabbit
• Clonality: Polyclonal
• Tested applications: ELISA, IF, IHC, WB
• Reactivity: Human
• Isotype: IgG
• Immunogen: SFRP1 antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to a 12 aa region of human Sfrp1 protein.
• Concentration: 1.0 mg/mL
• Dilution range: ELISA: 1:5,000 - 1:15,000, IHC: 1:800, IF: Use at a concentration of 5 µg/mL, WB: 1:200-1:2,000
• Form/Appearance: Liquid (sterile filtered)
• Purity: This affinity purified antibody is directed against human SFRP protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification. A BLAST analysis was used to suggest reactivity with this protein from human based on 100% homology for the immunogen sequence. Expect cross reactivity with SFRP1 from mouse, rat and bovine sources as only a single amino acid residue change is found within the immunogen sequence (91% positive by BLAST). Cross reactivity with SFRP1 homologues from other sources has not been determined.
• Conjugation: Unconjugated
• UniProt ID: Q8N474
• NCBI: 56117838
• 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-SFRP1 antibody, SFRP-1, secreted frizz
• Note: For research use only
• Application notes: This affinity purified antibody has been tested for use in ELISA, western blot, and IHC. This antibody is suitable for immunofluorescence. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 37 kDa in size corresponding to Sfrp1 by western blotting in the appropriate cell lysate or extract.
• Expiration Date: 12 months from date of receipt.

Biorbyt's Affinity Purified anti-Human SFRP1 antibody was used at a 1:800 dilution for 20 min to detect SFRP in human dermal hypertrophic scar tissue. Tissue was formalin-fixed followed by heat mediated antigen retrieval prior to blocking. HRP Gt-a-Rabbit IgG (p/n orb347673) is suitable for secondary antibody detection.

ELISA results of purified Rabbit anti-SFRP1 Antibody tested against BSA-conjugated peptide of immunizing peptide. Each well was coated in duplicate with 0.1 µg of conjugate. The starting dilution of antibody was 5 µg/ml and the X-axis represents the Log10 of a 3-fold dilution. This titration is a 4-parameter curve fit where the IC50 is defined as the titer of the antibody. Assay performed using 3% fish gel, Goat anti-Rabbit IgG Antibody Peroxidase Conjugated (Min X Bv Ch Gt GP Ham Hs Hu Ms Rt & Sh Serum Proteins) (p/n orb347654) and TMB ELISA Peroxidase Substrate (p/n orb348651).

Western blot using Biorbyt's Affinity Purified anti-SFRP1 antibody shows detection of a band ~37 kDa (arrowhead) corresponding to SFRP1 in lysates from human cultured airway epithelial cells. Lysates were run on a SDS-PAGE and transferred onto nitrocellulose followed by reaction with a 1:230 dilution of anti-SFRP1 antibody overnight at 4°C. Signal was detected using standard techniques.
