Key=background, value=Interleukin-25 (IL-25), also known as interleukin-17E (IL-17E), is a protein that in humans is encoded by the IL25 gene. It is a cytokine that belongs to the IL-17 cytokine family and mapped to 14q11.2. IL-25 is secreted by type 2 helper T cells (Th2) and mast cells. It has been found that IL-25 can induce Th2-type cytokine expression and production by non-T, non-B accessory cells that express high levels of major histocompatibility complex class II and low levels of Cd11c. This cytokine also can induce NF-κB activation, and stimulate the production of IL8. What’s more, IL-25 is an important molecule controlling immunity of the gut and has been implicated in chronic inflammation associated with the gastrointestinal tract.

What do you suggest using for controls/calibrators for EK0793?

Verified customer

Asked: 2021-01-26

Answer

Unfortunately, we could only provide recombinant proteins as positive controls which are compatible only with our ELISA kits. For controls such as serum, plasma, we suggest reviewing relevant publications for how to prepare them.

Question

Q: how are cell lysates prepared for use in Picokine® ELISA kits?

S. Clark

Verified customer

Asked: 2020-06-11

Answer

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 affect immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question

Can EK0789 and EK0793 be used with skin biopsies? If yes, is there a need to modify the protocol?

Verified customer

Asked: 2019-03-27

Answer

Our lab has not worked on skin biopsies using the Human IL-17C ELISA Kit PicoKine™ (EK0789) and Human IL-17E/IL-25 ELISA Kit PicoKine™ (EK0793). We suggest you to run a pilot test using the kits. The following is the suggested sample preparation protocol; 1. Mince skin biopsies and then rinse skin biopsies in ice-cold PBS. 2. Place minced skin biopsies in tissue homogenizer. 3. Add ice-cold PBS. For a 0.5g piece of tissue, add 5ml of ice-cold PBS (Volumes of PBS must be determined in relation to the amount of skin biopsies present.) 5. Homogenize for several minutes at high speed. 6. Sonicate until no skin biopsies chunks remain. 7. Centrifuge at ~10000 x g for 10 minutes. The centrifugation force and time can be varied depending on the sample type. 8. Aspirate supernatant. 9. Aliquot supernatant and store at -20°C. There is no need to adjust the main protocol.

Question

Q: Can IL-17E ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

Verified Customer

Verified customer

Asked: 2019-03-09

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 assessd 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.

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-17E for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question

Q: What is the optimal O.D. value for IL-17E ELISA kit? I used your IL-17E 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-17E even though the O.D. values are not very high?

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. what you should focus on 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 changeing 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-17E ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of IL-17E that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question

Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis IL-17E using the EK0793 Human IL-17E Picokine® ELISA Kit?

Answer

A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may affect 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 in order to prevent protein degradation.

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.
