9 Customer Q&As for Human CD169/SIGLEC-1/Sialoadhesin ELISA Kit PicoKine™

Question

Q: is it okay to use citrate plasma as samples in Human CD169 Picokine® ELISA Kit (Catalog # EK1304)?

W. Hall

Verified customer

Asked: 2020-09-09

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can bind metal ions from the functional domain of CD169 causing disruption of its protein structure. CD169 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 CD169 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: if the enzyme conjugated CD169 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 CD169 antigen?

Verified Customer

Verified customer

Asked: 2020-03-27

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: we need your recommendation regarding the dilution ratio of serum samples for detection of CD169 in Human serum? I am trying to measure a a number of analytes and it requires 100ul of diluted samples for each well. We have limited sample volumes so we like to dilute as much as possible.

Verified Customer

Verified customer

Asked: 2019-02-26

Answer

A: having little idea about 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 CD169 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 CD169 ELISA kit? I used your CD169 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 CD169 even though the O.D. values are not very high?

Verified Customer

Verified customer

Asked: 2016-10-04

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. 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 CD169 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of CD169 that can be declared/interpreted as positive by the above standard is 10pg/ml.
