Target: Bovine Host: Goat Antibody Format: Whole IgG Specificity: IgG (H+L) Conjugate: Cyanine Cy™3 Product Category: Whole IgG Affinity-Purified Antibodies Clonality: Polyclonal RRID: AB_2337305 Warning: Bovine serum albumin (BSA) and dry milk may contain IgG. Secondary antibodies directed against alpaca, bovine, goat, horse, or sheep react with bovine IgG. Therefore, use of BSA or milk to block or dilute these antibodies may significantly increase background and/or reduce antibody titer. For blocking, normal serum (5% v/v) from the host species of the labeled secondary antibody is recommended. 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 immunoelectrophoresis and/or ELISA, the antibody reacts with whole molecule bovine IgG. It also reacts with the light chains of other bovine immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins. The antibody may cross-react with immunoglobulins from other species. 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: 1:100 - 1:800 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. Cy3 is brighter, more photostable, and gives less background than other orange-red fluorescing dye conjugates. Cy3 conjugates can be excited maximally at 550 nm, with peak emission at 570 nm. For fluorescence microscopy, Cy3 can be visualized with traditional tetramethyl rhodamine (TRITC) filter sets, since the excitation and emission spectra are nearly identical to those of TRITC. We recommend Cy3 as a brighter alternative to TRITC. Cy3 can be excited to about 50% of maximum with an argon laser (514 nm or 528 nm lines), or to about 75% of maximum with a helium/neon laser (543 nm line) or mercury lamp (546 nm line). Cy3 has been used with fluorescein for double labeling; however, the use of a narrow band-pass emission filter for fluorescein is recommended to minimize Cy3 fluorescence in the FITC filter set. Cy3 can also be paired with Alexa Fluor® 647 for multiple labeling when using a confocal microscope. However, a better choice for multiple labeling is Rhodamine Red-X because its fluorescence is midway between a green fluorescing dye (like Alexa Fluor® 488) and a far-red-fluorescing dye like Alexa Fluor® 647.This product is for IN VITRO RESEARCH USE ONLY.
