Description

The Thermo Scientific Pierce Rapid Mouse Antibody Isotyping Kit is a single-use, cassette-based kit for 5-minute lateral-flow assay determination of mouse monoclonal antibody class and subclass identity.

This antibody isotyping kit uses cartridges that provide a color-readout of the monoclonal antibody isotype within five minutes after pipetting a small amount of diluted culture supernatant or ascites fluid sample into the sample well. The kit determines mouse IgG1, IgG2a, IgG2b, IgG3, IgA, IgM.

Features of the Pierce Rapid Mouse Antibody Isotyping Kit:

Long shelf life—stable for at least one year at room temperature
Single-step—add diluted antibody sample to the loading-well of cassette
Fast—within 5 minutes a band appears that indicates the antibody isotype
Sensitive—detect antibodies in tissue culture media or ascites fluid samples at any concentration greater than 10 ng/mL
Specific—assay does not cross-react with fetal bovine serum (FBS)
Reliable—results are similar to the standard ELISA-based isotyping assays

Each Pierce Rapid Isotyping Kit assay is performed by simply adding a properly diluted tissue culture supernatant or mouse ascites sample to the well of the small cassette. Gold conjugates embedded in the cassette form specific class- and subclass-soluble complexes with the antibodies in the sample. These complexes travel the length of the membrane and are resolved on the anti-isotype and class-specific antibody-impregnated membrane. Results are displayed as a red band indicating the antibody isotype or subclass.

Determining the class and subclass of a monoclonal antibody is useful in planning the best immunoglobulin purification method. For example, mouse IgA and IgM are best purified by size (i.e., gel exclusion) or using immunoaffinity separation columns. Mouse IgG2a and IgG2b are purified with immobilized Protein A at pH 7-8, while Mouse IgG1 binds best to Protein A at pH 8-9. Immunoglobulin that contains kappa light chains can be purified using immobilized Protein L.

The Pierce Rapid Isotyping Kit is compatible with both tissue culture supernatant and mouse ascites fluid, and is more sensitive than conventional latex-bead based dipstick assays and much faster than ELISA-based isotyping assays. The kit requires only 0.5µL ascites fluid, 5 to 55µL of cell culture supernatant or 1.5ng of purified antibody.
