ELISA kit for measuring Dermatophagoides spp.   Group 2 allergens, Der p 2

*Not recommended for allergen quantification in samples   that contain multiple house dust mite species

Antibodies:

1D8/7A1

Sensitivity:

0.2ng/ml

Limit of Detection:

0.8ng/ml

Assay Performance:

Intra-assay CV% of 8.9; Inter-assay CV% of 30

Contents:

Monoclonal antibody 1D8, Universal   Allergen Standard, Biotinylated antibody 7A1; sufficient reagents for 10   plates.

Storage:

Store at 4°C.

Not Provided:

50mM Carbonate/Bicarbonate buffer, pH 9.6

  Phosphate Buffered Saline, pH 7.4, containing 0.05% Tween 20 (PBS-T)

  Bovine Serum Albumin

  Streptavidin-Peroxidase

  1mM ABTS in 70mM citrate-phosphate buffer, pH 4.2

Notes:

Der p 2 allergen concentration  can   only be determined in  D. pteronyssinus samples using the components of   this kit. Not recommended for use with samples that potentially contain both   D. pteronyssinus and D. farinae species of dust mite. Use Der p 1 (product   code: EL-DP1) and Der f 1 (product code: EL-DF1) kits to quantify the   concentration of both house dust mite species in a sample.

Der f 2 allergen concentration is   underestimated using this kit. To quantify the concentration of Der f 2 in a   single species sample, the use of the Der f 2 kit (product code: EL-DF2) is   recommended.
