Target Details CD14 is a surface protein preferentially expressed on monocytes/macrophages. It binds lipopolysaccharide binding protein and recently has been shown to bind apoptotic cells. Alternative splicing results in multiple transcript variants encoding the same isoform.

RGD 620588
MGI 88318


Intra-assay Precision (Precision within an assay): CV%<8%

Three samples of known concentration were tested twenty times on one plate to assess.

Inter-assay Precision (Precision between assays):CV%<10%

Three samples of known concentration were tested in twenty assays to assess.




To assess the linearity of the assay, samples were spiked with high concentrations of human sCD14 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.


Typical Data


These standard curves are provided for demonstration only. A standard curve should be generated for each set of samples assayed.

Q&A and Customer Reviews


For item CSB-E13199h,if the kit detects both soluble and membrane bound CD14. Would you have any testing data that addresses this question that you could share?

Thanks for your inquiry.
CD14 exists in two forms, one anchored to the membrane by a glycosylphosphatidylinositol tail (mCD14), the other a soluble form (sCD14).
Soluble CD14 either appears after shedding of mCD14 or is directly secreted from intracellular vesicles.
CSB-E13199h This kit is designed according to: It detects soluble form.
For serum and plasma samples, CD14 usually exists in soluble form and the kit detects soluble CD14.
For cell samples, after cellwall breaking, the hydrophobic region of the membrane protein will be closed, and the soluble component can be detected at this time.
We tested serum and plasma samples before and the test value is 3.75--7.5ng/ml under 1:200 dilution.
The final concentration is 750--1500ng/ml.
Pls let me know if you have any further questions. Thank you.
