10 Customer Q&As for Rat IL-18/IL-1F4/Interleukin-18 ELISA Kit PicoKine™


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

W. Wilson

Verified customer

Asked: 2020-11-17


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

Q: is it okay to use citrate plasma as samples in Rat IL-18 Picokine® ELISA Kit (Catalog # EK0592)?

Verified Customer

Verified customer

Asked: 2020-09-22


A: Chelating agents such as EDTA, Heparin and Citrate can bind metal ions from the functional domain of IL-18 causing disruption of its protein structure. IL-18 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-18 ELISA, treating samples with different anticoagulants and decided that heparin or EDTA can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Has the serum / plasma MRD (Minimal Required Dilution) been calculated for EK0592 kit?

Verified customer

Asked: 2020-04-05


The serum / plasma MRD (Minimal Required Dilution) for Rat IL-18 ELISA Kit PicoKine EK0592 is 1:1.

Boster Scientific Support

Answered: 2020-04-07


Q: can you suggest the dilution ratio of serum samples for detection of IL-18 in Rat serum? I am trying to measure a few parameters and it requires 100ul of diluted samples for each well. We have low serum quantitys so we like to dilute as much as possible.

V. Mitchell

Verified customer

Asked: 2019-08-24


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-18 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.

Was baculovirus expression system used for the manufacturing process of EK0592? How about recombinant Rat IL-18 standard and antibodies? Is this a recombinant protein?

Verified customer

Asked: 2019-05-15


For the Rat IL-18 ELISA Kit PicoKine™ (EK0592), E.coli expression system is used and it is a recombinant protein.

Boster Scientific Support

Answered: 2019-05-16


Has EK0592 been validated on urine samples?

Verified customer

Asked: 2019-05-15


We have not tested nor validated the Rat IL-18 ELISA Kit PicoKine™ (EK0592) with urine sample. In theory the ELISA kit will work for all sample types if the target protein is present at a level that falls within the linear range of the ELISA kit detection range. For sample types that we have not tested for, we suggest to run pilot experiments and decide the optimal sample dilution.

Answered: 2019-05-16


Q: Can IL-18 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

Verified Customer

Verified customer

Asked: 2017-06-15


A: Unfortunately, Boster Bio has not routinely validated tissue homogenates as a sample type for ELISA kits. This does not mean that ELISA kits are not suitable for other sample types than we have tested: it means further investigation is required. One will need to perform a spike and recovery study to determine if an unvalidated sample type will work with a particular kit. To perform a spike and recovery experiment, one should divide a sample into two aliquots. In one of the aliquots, the user should spike in a known amount of the kit standard. a dilution series is performed comparing the spiked versus the unspiked sample. Generally, samples with expected recovery and linearity between 80-120% are considered acceptable. This method can be used to validate any sample type that has not been evaluated by Boster Bio. for a more detailed spike and recovery protocol, please contact technical support.
Note: acceptable ranges should be determined individually by each laboratory. Additionally, technical support can help determine if a buffer component is not compatible with a given ELISA kit. please check the Citations tab on the product webpage for peer-reviewed papers utilizing a wide range of sample types. We also have an innovator's reward program where if the user validates our ELISA kits in applications or samples previously not validated by Boster Bio or other users, and share such information with us by submit a review, we will reward the user's efforts with a free antibody or ELISA kit from our catalog. Biocompare.com will also give $20 Amazon giftcard as an additional reward, if the review is submitted there as well.

Q: can you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?

H. Williams

Verified customer

Asked: 2017-04-16


A: for those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are included in the product insert. Components in lysate and lysis buffer can have an affect on immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Boster Scientific Support

Answered: 2017-04-16


Q: if the enzyme conjugated IL-18 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-18 antigen?

Verified Customer

Verified customer

Asked: 2016-03-19


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.

Boster Scientific Support

Answered: 2016-03-19


Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for quantification IL-18 using the EK0592 Rat IL-18 Picokine® ELISA Kit?

D. Davis

Verified customer

Asked: 2014-01-28


A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may alter 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 repeat freeze-thaw cycles with the stored samples to avoid protein degradation.
