Goat Polyclonal Antibody

Specifications

Product Data
Applications	ELISA, IHC, WB
Recommend Dilution	WB: 1:1,000-1:5,000 IHC: 1:500-1:2,500 ELISA: 1:2,000 - 1:10,000
Host	Goat
Clonality	Polyclonal
Immunogen	Protein A [Staphylococcus aureus]
Specificity	Anti-Protein A is an IgG fraction antibody purified from monospecific antiserum by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above.  Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Biotin, anti-Goat Serum as well as purified and partially purified Protein A [Staphylococcus aureus].  Cross reactivity against Protein A from other sources is unknown.
Formulation	0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2
Concentration	1.0 mg/mL - lot specific
Conjugation	Biotin
Storage Condition	Store vial at -20° C or below prior to opening. This vial contains a relatively low volume of reagent (25 µL). To minimize loss of volume dilute 1:10 by adding 225 µL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.
Background	Biotin is widely used throughout the biotechnology industry to conjugate proteins for biochemical assays. Biotin's small size typically does not affect the biological activity of protein upon biotinylation. Biotinylated proteins of interest can be enriched from a sample due to highly stable interactions. Biotin conjugated anti-Protein A antibodies are used as an amplifying reagent in immunohistochemistry, microarray assays, ELISAs, blots, and other applications.
Synonyms	goat anti-Protein A Antibody, Biotin Conjugated goat anti-Protein A Antibody, Protein A Biotin, Protein A BAC Antibody
Note	Anti-Protein A Biotin Conjugated has been tested by dot blot and western blot. This product is suitable to be assayed against 1.0 ug of Protein A in a standard capture ELISA using Peroxidase Conjugated Streptavidin #S000-03 and ABTS (2,2’-azino-bis-[3-ethylbenthiazoline-6-sulfonic acid]) code # ABTS-100 as a substrate for 30 minutes at room temperature.  A working dilution of 1:4,000 to 1:20,000 of the reconstitution concentration is suggested for this product.
