Antibody isotype determination

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.

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

  Ig isotyping coating (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
