Background of CEACAM5/CD66e
Carcinoembryonic antigen (CEA) is a complex immunoreactive glycoprotein with a molecular weight of 180,000 comprising 60% carbohydrate. It is found in adenocarcinomas of endodermally derived digestive system epithelia and in fetal colon.Carcinoembryonic antigen is one of the most widely used tumor markers in serum immunoassay determinations of carcinoma.

Question
Q: how many samples can be assayed in a Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2020-10-17
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 depends upon the kit used so please refer to each datasheet for details.

Question
Q: can I use citrate plasma as samples in Human CD66e Picokine® ELISA Kit (Catalog # EK0904)?
Verified Customer
Verified customer
Asked: 2020-07-19
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of CD66e causing degradation of its protein structure. CD66e 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 CD66e 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.

Question
Q: can you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?
P. Jha
Verified customer
Asked: 2020-05-26
Answer
A: for those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are present 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: What is the optimal O.D. value for CD66e ELISA kit? I used your CD66e 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 CD66e even though the O.D. values are not very high?
S. Kumar
Verified customer
Asked: 2019-07-04
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. typically, 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 CD66e ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of CD66e that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: how can I thaw whole blood sample for CD66e ELISA after freezing?
Verified Customer
Verified customer
Asked: 2019-04-26
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 CD66e for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: we need your recommendation regarding the dilution ratio of serum samples for detection of CD66e in Human serum? I am trying to measure a few parameters and it requires 100ul of diluted samples for each well. We have limited sample volumes so we like to dilute as much as possible.
M. Krishna
Verified customer
Asked: 2018-11-01
Answer
A: unable to know 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 CD66e 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.

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.

Verified Customer
Verified customer
Asked: 2014-09-01
Answer
This method is not recommended. It may cause errors when removing the final solution into separate cuvettes, and the color will decay with time, O.D. absorbance at 450nm of different wells should be read at the same time.

Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for quantification CD66e using the EK0904 Human CD66e Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2014-02-24
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 right after 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 limit protein degradation.
