Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Mouse IL-21/Interleukin-21 ELISA Kit PicoKine™ within the same batch/lot to ensure the consistency of the kits' performances. ELISA intra assay consistency is measured using wells from the same plate/assay kit. ELISA inter assay consistency is measured using wells from different plates from the same batch production/lot.

5 Customer Q&As for Mouse IL-21/Interleukin-21 ELISA Kit PicoKine™
Question
What would be the starting dilution of this antibody EK0797?
Verified Customer
Verified customer
Asked: 2020-04-09
Answer
We would recommend for the product EK0797 kit a 2 fold dilution for plasma samples

Question
Q: if the enzyme conjugated IL-21 antibodies are mixed with the substrate, will that change the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the IL-21 antigen?
Verified Customer
Verified customer
Asked: 2020-04-06
Answer
A: The enzyme is always active. Avoid contaminating the substrate with enzyme prior to the incubation otherwise it compromises the assay with false positive signal.

Question
Q: how to thaw whole blood sample for IL-21 ELISA after freezing?
Verified Customer
Verified customer
Asked: 2020-03-17
Answer
A: do not freeze and thaw whole blood. erythrocytes are fragile and, if frozen and thawed, will undergo hemolysis rendering the samples useless. To keep your blood samples to test IL-21 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Asked: 2018-10-02
Answer
A: we recommend you this article on ELISA data analysis. bosterbio.com/ELISA-data-analysis-instructions. Boster also provides a free tool that you can use to analyze ELISA data. bosterbio.com/biology-research-tools/ELISA-data-analysis-online

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
C. Mitchell
Verified customer
Asked: 2018-03-11
Answer
A: although the vials are bottled using aseptic techniques, heat-treated vials, and sterile stock solutions, they are not considered or guaranteed to be sterile. If sterile material is required for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.
