"This kit was very straightforward and easy to use. Followed the protocol given in the kit...Straight forward experiment, no tips needed. Kit worked great - positive control was clearly positive. Nothing bad about the kit, although our experimental results were negative. We would buy this kit or similar ELISA kits again from BosterBio."

8 Customer Q&As for Human IL-28A ELISA Kit PicoKine™

Question

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

Verified Customer

Verified customer

Asked: 2020-11-14

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 depends upon the kit used so please refer to each datasheet for details.

Answered: 2020-11-14

Question

Q: if the enzyme conjugated IL-28A antibodies are mixed with the substrate, will that convert the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the IL-28A antigen?

Verified Customer

Verified customer

Asked: 2020-08-05

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

For this Human IL-28A ELISA Kit PicoKine; has this been tested to have a cross reactivity with human IL-28B?

Verified Customer

Verified customer

Asked: 2019-06-11

Answer

The product Human IL-28A ELISA Kit PicoKine has not been tested to have cross reactivity with human IL-28B. However, human IL-28A have very high sensitivity with human IL-28B at 96%, so there is a possibility that this kit will be also detecting IL-28B.

Question

Q: Can IL-28A ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

Z. Williams

Verified customer

Asked: 2018-06-01

Answer

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.

Question

Q: can you suggest the dilution ratio of serum samples for detection of IL-28A 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 quantitys so we like to dilute as much as possible.

Verified Customer

Verified customer

Asked: 2017-10-06

Answer

A: without knowing 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-28A 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: is it okay to use citrate plasma as samples in Human IL-28A Picokine® ELISA Kit (Catalog # EK0969)?

Z. Kaur

Verified customer

Asked: 2017-01-11

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can sequester metal ions from the functional domain of IL-28A causing disruption of its protein structure. IL-28A 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-28A ELISA, treating samples with a number of 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: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for quantification IL-28A using the EK0969 Human IL-28A Picokine® ELISA Kit?

Verified Customer

Verified customer

Asked: 2016-01-27

Answer

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 repetitive freeze-thaw cycles with the stored samples to avoid protein degradation.
