Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Peroxidase, anti-Goat Serum, Rat IgG, Rat IgG F(c) and Rat Serum. No reaction was observed against anti-Pepsin, anti-Goat IgG F(c), Rat IgG F(ab’)2 or Bovine, Horse, Human Serum Proteins.
Preservative: 0.01% Gentamicin Sulfate
Constituents: 10mg/ml BSA IgG and protease free), 0.15M Sodium Chloride, 0.02M Potassium Phosphate. pH 7.2
(Warning: use of sodium azide as a preservative will substantially inhibit the enzyme activity of horseradish peroxidase.)
Concentration information loading...
This product was prepared from monospecific antiserum by immunoaffinity chromatography using Rat IgG coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities, pepsin digestion and chromatographic separation.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Dot: Use at an assay dependent dilution.
Electron Microscopy: Use at an assay dependent dilution.
ELISA: 1/20000 - 1/200000.
IHC: 1/500 - 1/5000.
WB: 1/20000 - 1/200000.
This product has been assayed against 1.0 µg of Rat IgG in a standard capture ELISA using ABTS (2,2’-azino-bis-[3-ethylbenthiazoline-6-sulfonic acid]) as a substrate for 30 minutes at room temperature. A working dilution of 1/20000 to 1/200000 of the reconstitution concentration is suggested for this product for ELISA and Western blots and a 1/500 to 1/5000 for immunohistochemistry on tissue sections.
Suitable for other peroxidase-antibody based enzymatic assays requiring extremely low background levels, absence of F(c) mediated binding, lot-to-lot consistency, high titer and specificity.
Not tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
