Canine IL-4 Fast ELISA

Description

The Fast Canine IL-4 ELISA is a solid phase ELISA designed to measure canine IL-4 levels in cell culture supernatants, serum, and plasma. The main feature is that the kit uses our novel proprietary approaches to combine samples and detections into a one-step instead of the complicated traditional methods. It makes the assay simple, easy, accurate, and fast. The measurement can be finished in 2 hours, not 5-6 hours (Fig. 1). The detection range is from 78 to 5000pg/mL. The levels of canine IL-4 samples are parallel to the standard curves obtained using the kit standards linearly. These results indicate that this kit can be used to determine relative mass values for natural canine IL-4 protein.

 

Typical Data

This standard curve (R²=1) is provided for demonstration only. A standard curve should be generated for each set of samples assayed.

Sensitivity

The minimum detectable dose (MOD) of canine IL-4 is typically 50 pg/ml.
The Intra-CV is < 10%, the Inter-CV is < 10%.

Specificity

This assay recognizes natural and recombinant canine IL-4.
No-cross reactivity:
Canine IL-2; canine IL-6; bovine IL-4; cotton rat IL-4; equine IL-4; feline IL-4; human IL-4; mouse IL-4; porcine IL-4; rabbit IL-4; rat IL-4; rhesus macaque IL-4.
