10 Customer Q&As for Human IGFBP-1 ELISA Kit PicoKine™

Question

Q: if the enzyme conjugated IGFBP-1 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 IGFBP-1 antigen?

Verified Customer

Verified customer

Asked: 2020-03-23

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

Verified Customer

Verified customer

Asked: 2019-08-19

Answer

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

Question

Q: Can IGFBP-1 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

Verified Customer

Verified customer

Asked: 2019-04-11

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 needed. 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.

Question

Q: What is the optimal O.D. value for IGFBP-1 ELISA kit? I used your IGFBP-1 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 IGFBP-1 even though the O.D. values are not very high?

Verified Customer

Verified customer

Asked: 2019-03-28

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. in the above example, 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 IGFBP-1 ELISA kit to have sensitivity of 1pg/ml, that means the minimum amount of IGFBP-1 that can be declared/interpreted as positive by the above standard is 1pg/ml.

Asked: 2019-02-23

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 required 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 IGFBP-1 Picokine® ELISA Kit (Catalog # EK0382)?

D. Rodriguez

Verified customer

Asked: 2019-01-21

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of IGFBP-1 causing degradation of its protein structure. IGFBP-1 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 IGFBP-1 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.

Q: which procedure should I follow in order to thaw whole blood sample for IGFBP-1 ELISA after freezing?

T. Bhatt

Verified customer

Asked: 2018-06-27

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 IGFBP-1 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.
