7 Customer Q&As for Rat VE-Cadherin-5 Cdh5 ELISA Kit PicoKine™

Question

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

Verified Customer

Verified customer

Asked: 2019-12-22

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. regarding 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 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 VE-Cadherin ELISA kit to have sensitivity of 50pg/ml, that means the minimum amount of VE-Cadherin that can be declared/interpreted as positive by the above standard is 50pg/ml.

Question

Q: is it okay to use citrate plasma as samples in Rat VE-Cadherin Picokine® ELISA Kit (Catalog # EK1916)?

Verified Customer

Verified customer

Asked: 2019-08-28

Answer

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

Question

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

Verified Customer

Verified customer

Asked: 2019-08-08

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

Question

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

Verified Customer

Verified customer

Asked: 2019-06-28

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 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.

Question

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

Verified Customer

Verified customer

Asked: 2018-08-05

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 might differ by kit so please refer to each datasheet for details.

Question

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

M. Collins

Verified customer

Asked: 2018-07-31

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

Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis VE-Cadherin using the EK1916 Rat VE-Cadherin Picokine® ELISA Kit?

Verified Customer

Verified customer

Asked: 2017-07-02

Answer

A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample on priority basis collection when possible, or aliquot into single use volumes and store samples frozen. limit repetitive freeze-thaw cycles with the stored samples to prevent protein degradation.
