Technical Info

Whole IgG antibodies are isolated as intact molecules from antisera by immunoaffinity chromatography. They have an Fc portion and two antigen binding Fab portions joined together by disulfide bonds and therefore they are divalent. The average molecular weight is reported to be about 160 kDa. The whole IgG form of antibodies is suitable for the majority of immunodetection procedures and is the most cost effective.

Based on antigen-binding assay, Western blotting, and/or ELISA, the antibody reacts with the light chains on rat IgG and with those common to other rat immunoglobulins. Reaction is primarily with kappa light chains. The antibody does not react with the heavy chain of rat IgG. The antibody has been tested by ELISA to ensure minimal cross-reaction with bovine, goat, horse, human, mouse, rabbit and sheep immunoglobulins, but it may cross-react with immunoglobulins from other species.
Physical State: Freeze-dried solid

Storage and Rehydration: Store freeze-dried solid at 2-8°C. Rehydrate with the indicated volume of dH2O and centrifuge if not clear. Prepare working dilution on day of use. Product is stable for about 6 weeks at 2-8°C as an undiluted liquid.
Extended Storage after Rehydration: Aliquot and freeze at -70°C or below. Avoid repeated freezing and thawing. Alternatively, add an equal volume of glycerol (ACS grade or better) for a final concentration of 50%, and store at -20°C as a liquid.
Expiration date: one year from date of rehydration. The expiration date may be extended if test results are acceptable for the intended use.


Purity: The antibody was purified from antisera by immunoaffinity chromatography using antigens coupled to agarose beads.
Buffer: 0.01M Sodium Phosphate, 0.25M NaCl, pH 7.6
Stabilizer: 15 mg/ml Bovine Serum Albumin (IgG-Free, Protease-Free)
Preservative: 0.05% Sodium Azide

Suggested Working Concentration or Dilution Range:

1:50 - 1:200 for most applications

Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.

Cyanine Cy™2

Amax: 492 Emax: 510nm

Cy2 conjugates have maximum absorption/excitation at 492 nm and fluoresce with a peak around 510 nm in the green region of the visible spectrum like FITC conjugates (520 nm), but they are more photostable and less sensitive to pH changes than FITC. However, for mounting in aqueous media we recommend Alexa Fluor® 488 as the preferred green-fluorescing dye because it is brighter and more photostable than Cy2, FITC, and DyLight 488. A further disadvantage of using Cy2 with aqueous mounting media is its sensitivity to p-phenylenediamine, an anti-fading agent found in some commercial mounting media, which results in weak and diffused fluorescence after storage of stained slides. The main advantage of Cy2 conjugates is increased fluorescence in plastic mounting media.
