Information Based on antigen-binding assay and/or ELISA, the antibody reacts with the Fc portion of mouse IgG1 but not with other mouse IgG subclasses, mouse IgM, or the Fab portion of mouse immunoglobulins.No antibody was detected against non-immunoglobulin serum proteins.The antibody has been tested by ELISA and/or solid-phase adsorbed to ensure minimal cross-reaction with human, bovine and rabbit serum proteins, but it 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. Store at 2-8°C – do not freeze. Prepare working dilution on day of use. Expiration date: six months 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 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 R-Phycoerythrin
Amax: 488Emax: 580nmPhycoerythrin (R-PE) is among several kinds of light-harvesting phycobiliproteins found in red, blue-green, and cryptomonad algae. We offer R-PE, the form found in red macrophytic algae (seaweed). After phycobiliproteins are conjugated to secondary antibodies, there is little fluorescence quenching, which results in conjugates of high specific fluorescence compared with conventional fluorophore-antibody conjugates. R-PE can be excited by light over a wide range of the visible spectrum is highly water soluble, has a relatively low isoelectric point, and lacks potentially sticky carbohydrates.
It should be noted that the relatively high molecular weight of R-PE may preclude its use in procedures requiring good penetration into cells and tissues. It is predominantly intended for surface labeling of cells for flow cytometry.
