|Product Name||Human CD244/2B4 PicoKine™ ELISA Kit|
|Description||Sandwich High Sensitivity ELISA kit for Quantitative Detection of Human CD244/2B4. 96wells/kit, with removable strips.|
|Cite This Product||Human CD244/2B4 PicoKine™ ELISA Kit (Boster Biological Technology, Pleasanton CA, USA, Catalog # EK0926)|
*Our Boster Guarantee covers the use of this product in the above tested applications.
**For positive and negative control design, consult "Tissue specificity" under Protein Target Info.
|Immunogen||Expression system for standard: NSO; Immunogen sequence: C22-R221|
|Cross Reactivity||There is no detectable cross-reactivity with other relevant proteins.|
|Pack Size||96wells/kit, with removable strips.|
*Sensitivity, or Lower Limit of Detection (LLD), is the minimum level of target protein the ELISA assay can detect. We measure 20 blank wells and if the O.D. value is 2 standard deviations higher than the blanks' average O.D. the sample can be deemed positive.
*This assay range is determined using common samples. For samples with low target protein concentrations, users can adjust the standard curve to extend the lower limit of assay range.
|Sample Type||cell culture supernates, cell lysates, serum and plasma (heparin, EDTA).
*The above listed samples are the ones valided with the assay. If you do not see your sample of interest listed, as long as there is enough level of target protein present in the sample, this Picokine™ ELISA kit should detect it.
**For protocol and tips regarding preparing your sample of interest, please check our ELISA sample preparation guide.

Typical Data Obtained from Human CD244/2B4 PicoKine™ ELISA Kit
(TMB reaction incubate at 37°C for 25-30min)
*The typical data is obtained from Boster's internal QC result and for reference only. It may differ from the lab test results of the end users. It is more important that the user's lab test results reflect the same linearity demonstrated in the typical data than achieving exactly the same O.D. values.
