SENSISpec Walnut ELISA Kit (48 Wells) – HU0030048

SENSISpec Walnut ELISA Kit is a sandwich ELISA-format test kit designed for quantitative detection of walnut residues in processed food products (cookies, cereals, ice cream, chocolate, etc.). Manufactured by Gold Standard Diagnostics and supplied in 48-well microtiter plate format.

The kit provides rapid results with a total incubation time of 60 minutes (3×20 minutes); detection is performed colorimetrically at 450 nm using the HRP-TMB system. Calibration is provided with standards at 0; 2; 6; 20; 60 ppm, with a detection limit of 0.35 ppm and a quantification range of 2-60 ppm.

The kit's cross-reactivity profile is particularly important: <0.003% cross-reactivity is observed with soybean, pine nut, peanut, sesame, and Brazil nut, while hazelnut shows 0.022%, chestnut 0.11%, and pecan nut 0.80% cross-reactivity. This profile should be considered when evaluating false positive risk in walnut analysis.

Suitable for food safety laboratories, production facility quality control units, and laboratories providing allergen testing services. Shelf life is 13 months; store at 2-8°C.
