Identify and measure antibodies

ELISA provides a fast, sensitive and convenient method to identify and quantify antibody classes, subclasses, and isotypes during and after hybridoma development to assess immune response.

Invitrogen immunoglobulin-specific ELISA kits and isotyping ELISA kits enable accurate quantitation and high throughput for testing more samples at a time. Select single-isotype or multi-isotype (isotyping) kits involving IgG, IgA, IgE, and IgM subclasses and isotypes from human, mouse and rat species.

Choose a kit featured on this page, or select an immunoglobulin ELISA kit from among all target-specific ELISA kits using the following selection guide.

Antibody isotype determination

Invitrogen ELISA kits for isotyping are available for mouse and rat in two different formats:

  Ig Isotyping Instant ELISA kits Ig Isotyping Uncoated ELISA kits
Format Coated ELISA kit (Instant ELISA format) Uncoated ELISA kit
Features Addition of sample is all that is required, because coating & detector antibodies are already lyophilized on the plate. Antibodies come in vials and are not pre-coated onto the well plate, allowing you to modify the assay and protocol.
Features Measure 10 -12 samples per plate
Easy: Only 1 wash step
Fast: 2 hours total incubation
Size: 2 x 96 tests
Measure 10 -12 samples per plate
Less expensive
Customizable well pattern
Size: 10 x 96 tests
Isotypes IgG1, IgG2a, IgG2b, IgG3, IgA, IgM and kappa and lambda IgG1, IgG2a, IgG2b, IgG3, IgA, IgM and kappa and lambda
Mouse kits 88-50660-22 88-50630-86
88-50630-88 (with plates)
Rat kits 88-50650-22 88-50640-86
88-50640-88
