Fluorescein-Conjugated Goat Igg Fraction to Mouse Immunoglobulins (IGG,IGA,IGM)

Not yet rated

Product is the lyophilized powder of fluorescein-5-isothiocyanate (FITC "Isomer I")-conjugated goat IgG fraction to mouse immunoglobulins (IgG,IgA,IgM) and buffer salts.

Background Information
IgG is the most abundant immunoglobulin composed of two heavy chains and two light chains. Each molecule has two antigen binding sites. IgG has 4 subclasses: IgG1 (66%), IgG2 (23%), IgG3 (7%) and IgG4 (4%). IgM constitutes about 10% of serum immunoglobulins. IgM (with IgD) is the major immunoglobulin expressed on the surface of B cells. Monomeric IgA constitutes 5-15 % of the serum immunoglobulins whereas dimeric IgA is localized to mucosa surfaces.

Fluorescein-Conjugated Goat IgG Fraction to Mouse Immunoglobulins (IgG, IgA, IgM) is suitable for use as a reagent in immunofluorescence assays (IFA), cell staining (fluorescent microscopy and cell sorting), immunostaining of acetone-fixed frozen and formalin-fixed, paraffin-embedded tissue sections, and blot immunostaining. F(ab')2 fragments are recommended for staining of cells or tissues which contain Fc receptors. Affinity purified antibodies are recommended to avoid non-specific binding from the inherent antibodies of host animals.

Recommended Use
Reconstitute product with 2.0 mL of deionized or distilled water. Gentle swirling may be used to speed rehydration. Avoid vigorous shaking of the reconstituted material.

Typical Working Concentration
Suggested working dilutions: 1:100 - 1:400 for Tissue Staining; 1:250 - 1:1,000 for Immunoblotting; 1:1,000 - 4,000 for ELISA
