Application Details

Comment:

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.

Assay Time: 2 h

Plate: Pre-coated

Protocol: This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Insulin Like Growth Factor Binding Protein 4 (IGFBP4) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Insulin Like Growth Factor Binding Protein 4 (IGFBP4) and unlabeled Insulin Like Growth Factor Binding Protein 4 (IGFBP4) (Standards or samples) with the pre-coated antibody specific to Insulin Like Growth Factor Binding Protein 4 (IGFBP4). 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 Insulin Like Growth Factor Binding Protein 4 (IGFBP4) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Insulin Like Growth Factor Binding Protein 4 (IGFBP4) in the sample.

Assay Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Insulin Like Growth Factor Binding Protein 4 (IGFBP4) were tested 20 times on one plate, respectively
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Insulin Like Growth Factor Binding Protein 4 (IGFBP4) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%

Restrictions: For Research Use only

Handling

Handling Advice: The Stop Solution is acidic. Do not allow to contact skin or eyes. Calibrators, controls and specimen samples should be assayed in duplicate. Once the procedure has been started, all steps should be completed without interruption.

Storage: 4 °C,-20 °C

Storage Comment: -20°C. Bring all reagents to room temperature before beginning test. The kit may be stored at 4°C for immediate use within two days upon arrival. Reseal any unused strips with desiccant pack. Minimize freeze/thaw cycles.

Expiry Date: 4-8 months
