10 Customer Q&As for Human WISP1/CCN4 ELISA Kit PicoKine™

Question

Q: Can WISP1 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

R. Turner

Verified customer

Asked: 2020-10-18

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 valid 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 view 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: we need your suggestion regarding the dilution ratio of serum samples for detection of WISP1 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.

Y. Jha

Verified customer

Asked: 2020-09-06

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 WISP1 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: What is the optimal O.D. value for WISP1 ELISA kit? I performed your WISP1 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 WISP1 even though the O.D. values are not very high?

B. Banerjee

Verified customer

Asked: 2020-04-26

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. a point of focus should be is whether your sample O.D. values are statistically significantly higher than your blank values. in the example mentioned, 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. 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 WISP1 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of WISP1 that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question

Q: what is the protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?

Verified Customer

Verified customer

Asked: 2019-06-25

Answer

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

Question

Q: is it okay to use citrate plasma as samples in Human WISP1 Picokine® ELISA Kit (Catalog # EK1204)?

N. Jha

Verified customer

Asked: 2017-07-17

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of WISP1 causing degradation of its protein structure. WISP1 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 WISP1 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.

Answered: 2017-07-17

Question

Q: if the enzyme conjugated WISP1 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 WISP1 antigen?

Verified Customer

Asked: 2015-11-04

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

Q: how can I thaw whole blood sample for WISP1 ELISA after freezing?

Verified Customer

Verified customer

Asked: 2014-05-27

Answer

A: we do not recommend freezing 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 WISP1 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.
