Product details

ProductELISpot Plus: Human IL-21 (ALP)
ApplicationELISpot
AnalyteIL-21
ReactivityHuman, Non-human primates
SpecificityThis kit is based on a matched pair of mAbs specific for human IL-21.
Cross-reactivityThe mAbs react with human IL-21 and cross-react with IL-21 from non-human primates (NHP). For more information please check the Cross-reactivity guide section below.

Shipping and Storage

ShippingShipped at ambient temperature.
StorageStore antibodies, enzyme conjugate, and substrate at 4-8 °C upon receipt. Plates may be kept at room temperature.
Shelf lifeAt least 18 months from date of receipt.
PBMC were incubated for 20 h in the absence (250,000 cells/well) or presence (50,000 cells/well) of PHA and the number of cells secreting IL-21 was analyzed by ELISpot.

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.

IL-21

Analyte description

Interleukin 21 (IL-21) is primarily secreted by CD4 T cells (particularly follicular T cells and Th17) and is an important regulator of immune responses. For Th17 cells, IL-21 is an autocrine regulator sustaining Th17 development. IL-21 also regulates the development of other T cells as well as B cells, NK cells, and dendritic cells. Areas of particular interest for research on IL-21 include autoimmune and inflammatory diseases, cancer research, and basic studies on, e.g., B cells and T cells, especially on Th17 cells.
