LS-F56641 is a 96-well enzyme-linked immunosorbent assay (ELISA) for the detection of Human FGF4 in samples of Plasma and Serum. It is based upon a Custom assay principle and can be used to detect levels of FGF4 as low as 1.56 picograms per milliliter.

All LSBio Custom kits have been predesigned and all necessary components, including antibodies and standards have been identified. Upon receiving a custom kit order, the kit will be assembled and quality control tested before being shipped out. Kit assembly and testing typically takes 4 to 6 weeks. In most cases the final kit is based on the Sandwich assay principle, with a few being EIA Competition based. Specifications such as Range, Sensitivity, and Precision are defined upon completion. In the event that the custom kit cannot be successfully developed with 6 weeks of the order date, the customer will be notified and the order canceled at no cost.
