Information Based on immunoelectrophoresis and/or ELISA, the antibody reacts with the Fc portion of goat IgG heavy chain but not with the Fab portion of goat immunoglobulins.No antibody was detected against non-immunoglobulin serum proteins.The antibody may cross-react with immunoglobulins from other species.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.
Usage Physical State: Freeze-dried solid Storage and Rehydration: Store freeze-dried solid at 2-8°C. Rehydrate with the indicated volume of dH2O (see product specification sheet) 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:1:100 - 1:800 for most applicationsDilution 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.
Conjugate DyLight? 405
Amax: 400Emax: 421nmDyLight 405-conjugated secondary antibodies are excited maximally at about 400 nm and fluoresce with a peak at about 421 nm. They are very bright and photostable, but their optimal use is limited to microscopes or flow cytometers equipped with a 405 nm laser and a 420 nm emission filter. Under these conditions, it is possible to perform effective 4-color imaging with good color separation, good photostability, and high sensitivity. The combination of DyLight 405, Alexa Fluor? 488, Rhodamine Red-X, and Alexa Fluor? 647 provides for maximum color separation. Another 4-color dye combination, which may be equally effective but has slightly less color separation, is DyLight 405, Alexa Fluor? 488, Cy3, and Alexa Fluor? 647. DyLight 405 conjugates are an excellent choice for blue-fluorescing secondary antibodies in multi-color labeling protocols.
