8 Customer Q&As for Human ACE/Cd143 ELISA Kit PicoKine™

Question

Is EK0557 suitable with humane bronchoalveolare Lavage (BAL) samples?

Verified customer

Asked: 2021-02-12

Answer

Unfortunately, our lab hasn't worked with humane bronchoalveolare Lavage (BAL) samples using the Human ACE/Cd143 ELISA Kit PicoKine™ (EK0557). We are uncertain if the kit is able to work for BAL samples. Please run a pilot test if you want to try. In theory, if the expression level of the target protein in the sample falls in the assay range of the kits, the kits are able to detect the proteins in the samples.

Question

Q: if the enzyme conjugated CD143 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 CD143 antigen?

T. Bhatt

Verified customer

Asked: 2020-05-03

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: can I use EDTA plasma as samples in Human CD143 Picokine® ELISA Kit (Catalog # EK0557)?

Verified Customer

Verified customer

Asked: 2020-03-16

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can sequester metal ions from the functional domain of CD143 causing degradation of its protein structure. CD143 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 CD143 ELISA, treating samples with various anticoagulants and decided that heparin can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question

Q: we need your recommendation regarding the dilution ratio of serum samples for detection of CD143 in Human saliva? 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: 2019-12-07

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 CD143 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: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring CD143 using the EK0557 Human CD143 Picokine® ELISA Kit?

H. Anderson

Verified customer

Asked: 2018-05-01

Answer

A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may change 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.

Question

Can the Human ACE PicoKine™ ELISA Kit (EK0557) detect ACE2 as well as ACE1?

Verified Customer

Verified customer

Asked: 2017-04-26

Answer

The immunogen of the antibodies in the Human ACE PicoKine™ ELISA Kit is the recombinant human ACE protein(L30-L1261) and was designed to detect only ACE1.

Question

Q: What is the optimal O.D. value for CD143 ELISA kit? I used your CD143 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 CD143 even though the O.D. values are not very high?

Verified Customer

Verified customer

Asked: 2016-07-15

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 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 CD143 ELISA kit to have sensitivity of 5pg/ml, that means the minimum amount of CD143 that can be declared/interpreted as positive by the above standard is 5pg/ml.

Question

Q: Are Boster Bio recombinant proteins and antibodies sterile?

Verified Customer

Verified customer

Asked: 2014-02-24

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 a must for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.
