Human Leukocyte Elastase Inhibitor (LEI) ELISA Kit

The Human Leukocyte Elastase Inhibitor (LEI) ELISA Kit is specifically designed for the accurate detection of levels of LEI in human serum, plasma, and cell culture supernatants. This kit offers high sensitivity and specificity, ensuring dependable and reproducible results for a variety of research applications.LEI is an important protein that plays a key role in regulating inflammation and immune responses by inhibiting the activity of leukocyte elastase.

Dysregulation of LEI levels has been linked to various inflammatory conditions, making it a valuable biomarker for understanding and potentially treating these diseases.With its advanced technology and user-friendly design, the Human LEI ELISA Kit is an essential tool for researchers studying inflammatory diseases and seeking to uncover new therapeutic targets. Get accurate and reliable results with this innovative kit from Assay Genie.

Product Name:Human Leukocyte Elastase Inhibitor (LEI) ELISA Kit
Product Code:HUDL01705
Size:96 Assays
Target:LEI
Synonyms:SERPINB1, EI, ELANH2, LEI, M/NEI, MNEI, PI2, Serpin Peptidase Inhibitor Clade B Member 1, Anti-Elastase, Monocyte/Neutrophil Elastase Inhibitor
Detection Method:Sandwich
Range:0.312-20ng/mL
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)80-10291
EDTA plasma (n=5)81-9990
Heparin plasma (n=5)80-8984
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.
