    白蛋白(ALB)检测试剂盒
    ELISA Kit for Albumin (ALB)
    FOR IN VITRO AND RESEARCH USE ONLY, NOT FOR USE IN CLINICAL DIAGNOSTIC PROCEDURES!
    Organism species Oryctolagus cuniculus (Rabbit)
    Product No. CEB028Rb
    Sample type Serum, plasma and other biological fluids.
    Format 96T
    Assay length 2.5 hours
    Detection range 617.28-50000ng/mL The standard curve concentrations used for the ELISA’s were 50000ng/mL, 16666.67ng/mL, 5555.56ng/mL, 1851.85ng/mL, 617.28ng/mL
    Sensitivity The minimum detectable dose of this kit is typically less than 245.5ng/mL.
    Specificity
    This assay has high sensitivity and excellent specificity for detection of Albumin (ALB).
    No significant cross-reactivity or interference between Albumin (ALB) and analogues was observed.
    Recovery
    Matrices listed below were spiked with certain level of recombinant Albumin (ALB) and the recovery rates were calculated by comparing the measured value to the expected amount of Albumin (ALB) in samples.
    Matrix Recovery range (%) Average(%)
    serum(n=5) 88-103 99
    EDTA plasma(n=5) 82-101 97
    heparin plasma(n=5) 88-96 93
    Precision
    白蛋白(ALB)检测试剂盒Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Albumin (ALB) were tested 20 times on one plate, respectively.
    Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Albumin (ALB) were tested on 3 different plates, 8 replicates in each plate.
    CV(%) = SD/meanX100
    Intra-Assay: CV<10%
    Inter-Assay: CV<12%
    Linearity
    The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Albumin (ALB) 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) 96-105% 79-103% 91-105% 85-101%
    EDTA plasma(n=5) 98-105% 78-102% 95-104% 78-103%
    heparin plasma(n=5) 79-94% 78-95% 86-96% 94-103%
    Stability
    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.

    Test principle
    白蛋白(ALB)检测试剂盒This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Albumin (ALB) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Albumin (ALB) and unlabeled Albumin (ALB) (Standards or samples) with the pre-coated antibody specific to Albumin (ALB). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Albumin (ALB) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Albumin (ALB) in the sample.
