Human CD23/Fc epsilon RII Quantikine ELISA Kit Summary

• Background: The Quantikine Human CD23 immunoassay is a 4.5 hour solid phase ELISA designed to measure human soluble CD23 in cell culture supernates, serum, plasma, and urine. It contains NS0-expressed recombinant human CD23 (extracellular domain) and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human CD23 showed linear curves that were parallel to the st...andard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring soluble CD23.

Background

CD23, also known as Fc epsilon RII, is a type 2 transmembrane C-type lectin that binds IgE, CD21, CD11b and CD11c. It is expressed on a variety of hematopoietic cells and functions in allergic immune responses.

1. What is the difference between the Quantikine and Duoset ELISA kits?
   • Our Quantikine kits are fully optimized and validated for the sample types listed on the product specific webpage and datasheet, as this can vary between kits. Each kit is supplied ready to use with one pre-coated 96-well plate, a detection antibody directly conjugated to HRP, and all other necessary reagents. These kits are ideal for researchers who want the convenience of a ready to use and optimized ELISA product. Some of these kits are also available prepackaged in larger 6 and 50 plate sizes.Our DuoSet Kits, in contrast, are ELISA development kits containing the capture and detection antibody, the mass-value calibrated standard, and streptavidin-HRP to prepare approximately 5 or 15 plates. Ancillary reagents will need to be used/purchased, and for most kits, we will recommend one of our Ancillary Reagent Kits, which contain the reagents we use ourselves in-house. DuoSet kits are validated only for cell culture supernatant samples and therefore require further development and validation for accurate measurement in more complex samples such as serum and plasma. Our DuoSet Kits offer an economical, flexible alternative for the experienced ELISA user.
