Human Semaphorin 4A (SEMA4A) ELISA Kit

The Human Semaphorin 4A (SEMA4A) ELISA Kit is specifically designed for accurate detection of SEMA4A levels in human serum, plasma, and cell culture supernatants. With high sensitivity and specificity, this kit ensures reliable and reproducible results, making it suitable for a wide range of research applications.SEMA4A is a protein known to play a crucial role in immune responses and neurodevelopment. Dysregulation of SEMA4A has been linked to various autoimmune diseases, cancer, and neurological disorders, highlighting its importance as a biomarker for research and potential therapeutic development in these conditions.

Overall, the Human SEMA4A ELISA Kit provides researchers with a valuable tool for studying the role of SEMA4A in health and disease, offering accurate and precise quantification for meaningful results.

Product Name:Human Semaphorin 4A (SEMA4A) ELISA Kit
Product Code:HUDL02638
Size:96 Assays
Target:SEMA4A
Synonyms:CORD10, RP35, SEMAB, SEMB, Semaphorin-B, Sema Domain,Immunoglobulin Domain(Ig),Transmembrane Domain(TM)and Short Cytoplasmic Domain 4A
Detection Method:Sandwich
Range:0.312-20ng/m
Shelf Life:12 months
Note:For research use only
Recovery:Matrices listed below were spiked with certain level of recombinant the index and the recovery rates were calculated by comparing the measured value to the expected amount of the index in samples.
MatrixRecovery range (%)Average(%)
Serum (n=5)83-10091
EDTA plasma (n=5)91-9894
Heparin plasma (n=5)90-9994
Linearity:The linearity of the kit was assayed by testing samples spiked with appropriate concentration of the index and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
Sample 1:2 1:4 1:8 1:16
Serum (n=5) 82-96% 83-98% 81-99% 93-101%
EDTA plasma (n=5) 88-101% 86-95% 90-102% 80-93%
Heparin plasma (n=5) 80-91% 82-90% 95-104% 79-95%
Intra-assay Precision:Intra-Assay: CV <10%. 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision:Inter-Assay: CV <12%. 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
Stability:The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage conditions. Note: To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
