Low Sample Volume ELISA Kit for Glutamic Acid (Glu)

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Mini Samples Glutamic Acid (Glu) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Mini Samples Glutamic Acid (Glu) and unlabeled Mini Samples Glutamic Acid (Glu) (Standards or samples) with the pre-coated antibody specific to Mini Samples Glutamic Acid (Glu) . 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 Mini Samples Glutamic Acid (Glu) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Mini Samples Glutamic Acid (Glu) in the sample.

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Mini Samples Glutamic Acid (Glu) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Mini Samples Glutamic Acid (Glu) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV Inter-Assay: CV Inter-Assay: CV

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.

This assay has high sensitivity and excellent specificity for detection of Mini Samples Glutamic Acid (Glu) . No significant cross-reactivity or interference between Mini Samples Glutamic Acid (Glu) and analogues was observed.
