"I used this kit to detect a recombinant IL1RA in rat serum and it worked very well. The procedure was easy to follow and my standard curve was right on target. If needed we will order this kit and use it again. The kit was able to detect our rIL1RA but was less sensitive in detecting an altered formulation of the protein."

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement IL-1ra using the EK0782 Human IL-1ra Picokine® ELISA Kit?
Verified Customer
Asked: 2020-06-14
Answer
A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample right after collection when possible, or aliquot into single use volumes and store samples frozen. avoid repetitive freeze-thaw cycles with the stored samples in order to limit protein degradation.

Question
Q: how much samples can be assayed in a Picokine® ELISA Kit?
Verified Customer
Asked: 2020-05-27
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-1ra ELISA kit? I performed your IL-1ra 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. can I consider these samples contain IL-1ra even though the O.D. values are not very high?
L. Nelson
Asked: 2019-05-20
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. considering your assay, 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 proportion to your positive controls. normally, 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-1ra ELISA kit to have sensitivity of 2pg/ml, that means the minimum amount of IL-1ra that can be declared/interpreted as positive by the above standard is 2pg/ml.

Question
Q: we need your suggestion regarding the dilution ratio of serum samples for detection of IL-1ra in Human serum? I am trying to measure a few analytes and it requires 100ul of diluted samples for each well. We have limited sample volumes so we like to dilute as much as possible.
Verified Customer
Asked: 2018-05-29
Answer
A: unable to understand the physiological or pathological context of your samples we cannot recommend a dilution ratio without performing a pilot test with your samples. Here is how you can perform a pilot study on your own: perform a serial dilution of your samples on the IL-1ra ELISA kit to make sure you have a linear ascending curve followed by a plateau, which signifies the samples saturating the detection limit of the kit. Then you can pick the dilution ratios from samples in the linear part of the curve as your experimental dilution ratio.
If you are interested in using our ELISA service, you can also send us your sample and we will take care of everything for you. You can check our service details here: bosterbio.com/services/assay-services/ELISA-testing-service
Since you mentioned you have limited samples, our cost effective multiplex ELISA service would fit perfectly for your needs, where we can generate dozens of data points using as little as 25ul sample volume. Information on this service is also in the above link.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
Verified Customer
Asked: 2016-07-18
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 a must for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: can I use citrate plasma as samples in Human IL-1ra Picokine® ELISA Kit (Catalog # EK0782)?
P. Banerjee
Asked: 2015-09-14
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of IL-1ra causing degradation of its protein structure. IL-1ra may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes needed for detection and block the antigen antibody reaction. We have tested the IL-1ra 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.
