6 Customer Q&As for Human IL-5/Interleukin-5 ELISA Kit PicoKine™

Question

Q: Are Boster Bio recombinant proteins and antibodies sterile?

P. Mitchell

Verified customer

Asked: 2020-10-02

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.

Question

Q: how much samples can be assayed in a Picokine® ELISA Kit?

M. Surve

Verified customer

Asked: 2019-09-26

Answer

A: The Picokine® ELISA Kits will generally run a 7-point standard curve, non-specific binding wells, and 39 samples in duplicate. this may vary slightly by kit so please refer to each datasheet for details.

Question

Q: What is the optimal O.D. value for IL-5 ELISA kit? I performed your IL-5 ELISA on serum samples. For my positive control, I received an O.D. value of 0.826, while my negative control received a value of 0.136. I obtained both of these controls from the ELISA kit, where your kit's typical data shows O.D. values much higher than my positive control and your background is lower. My samples O.D. values are around 0.225 and the highest is only 0.357. is it safe to say these samples contain IL-5 even though the O.D. values are not very high?

Verified Customer

Verified customer

Asked: 2017-12-28

Answer

A: The absolute O.D. values may change according to incubation time. The more you incubate the higher the O.D. values are going to be. an important assessment should be is whether your sample O.D. values are statistically significantly higher than your blank values. in the above example, you could extend your development time in the substrate incubation step to obtain higher O.D. values, as long as your negative controls' O.D. values are not increasing faster in relation to your positive controls. typically, a sample with O.D. value 2 standard deviations higher than your negative controls can be considered positive. We calculate the sensitivity of this ELISA kit by converting cutoff O.D. value, calculated as the average of 20 negative controls plus 2 standard deviations of the 20 negative controls, into a concentration. in other words, when we claim this IL-5 ELISA kit to have sensitivity of 2pg/ml, that means the minimum amount of IL-5 that can be declared/interpreted as positive by the above standard is 2pg/ml.

Question

Q: can I use citrate plasma as samples in Human IL-5 Picokine® ELISA Kit (Catalog # EK0407)?

Verified Customer

Verified customer

Asked: 2017-12-22

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of IL-5 causing disruption of its protein structure. IL-5 may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes required for detection and block the antigen antibody reaction. We have tested the IL-5 ELISA, treating samples with various anticoagulants and decided that heparin or EDTA can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question

Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement IL-5 using the EK0407 Human IL-5 Picokine® ELISA Kit?

Verified Customer

Verified customer

Asked: 2017-08-17

Answer

A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample on-stat collection when possible, or aliquot into single use volumes and store samples frozen. avoid repeat freeze-thaw cycles with the stored samples to prevent protein degradation.

Question

Q: which procedure should I follow in order to thaw whole blood sample for IL-5 ELISA after freezing?

H. Bhasin

Verified customer

Asked: 2014-09-24

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-5 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.
