Product specifications

Intended use

This ELISpot Flex kit is intended for the enumeration of B cells secreting monkey IgA using the ELISpot assay. B cells secreting antigen-specific IgA, as well as B cells secreting IgA irrespective of antigen specificity (total IgA) can be enumerated. For research use only. Not for use in diagnostic procedures.

Serum/Plasma samples

Antigen-specific B cells can be enumerated in two alternative ways; by coating with antigen or by using biotinylated antigen in the detection step. For memory B cells, we recommend pre-stimulation with R848 and recombinant human IL-2 (both included).

Product details

ProductELISpot Flex: Monkey IgA (HRP)
ApplicationELISpot
AnalyteIgA
ReactivityNon-human primates
Specificity

This kit is based on a antibodies enabling specific detection of IgA from non-human primates (NHP).

Cross-reactivity

The antibodies react with human IgA and cross-react with IgA from NHP. For more information please check the Cross-reactivity guide section below.

Shipping and Storage

Shipping

Shipped at ambient temperature.

Storage

Store antibodies and enzyme conjugate at 4-8 °C upon receipt. R848 and IL-2 should be stored at -20 °C.

Shelf lifeAt least 18 months from date of receipt.
PBMC from cynomolgus macaque were pre-incubated for 72 h in the absence or presence of R848 and recombinant IL-2. The cells were then washed, added into ELISpot wells and analyzed for the secretion of total IgA (120,000 cells/well, overnight incubation).

The systems reactive with NHPs are either based on cross-reactive human kits or specifically developed monkey kits (NHP).

Cross-reactivity verification tests have been performed in ELISpot and/or ELISA by Mabtech and/or by others. Evaluations of assays with less solid evidence of cross-reactivity are shown as symbols within parentheses.

IgA

Analyte description

IgA (Immunoglobulin A) represents only 10-15% of the total Ig molecules in serum but is the predominating Ig isotype in secretions and in the gastrointestinal and urogenital tract. The IgA found in secretions (secretory IgA or sIgA) is commonly a dimer with two IgA molecules joined by the J chain. Secretory IgA is the most important Ig isotype in mucous surfaces, the area of entry for most pathogens.

Alternative namesImmunoglobulin A, IgA, A2M, IgA1
Cell typeB cell
