ELISA Kit for Leukotriene C4 (LTC4)



This assay has high sensitivity and excellent specificity for detection of Leukotriene C4 (LTC4).
No significant cross-reactivity or interference between Leukotriene C4 (LTC4) and analogues was observed.


Matrices listed below were spiked with certain level of Leukotriene C4 (LTC4) and the recovery rates were calculated by comparing the measured value to the expected amount of Leukotriene C4 (LTC4) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 85-101 89
EDTA plasma(n=5) 85-99 96
heparin plasma(n=5) 91-104 97


Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Leukotriene C4 (LTC4) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Leukotriene C4 (LTC4) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%


The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Leukotriene C4 (LTC4) 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) 95-103% 79-101% 78-88% 82-92%
EDTA plasma(n=5) 79-95% 80-90% 80-93% 93-101%
heparin plasma(n=5) 80-96% 98-105% 95-102% 94-102%


The stability of 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 condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.
