Background of CCL22/MDC

Macrophage-derived chemokine (MDC), also called Chemokine, cc motif, ligand 22 (CCL22) or Small inducible cytokine subfamily A, member 22 (SCY22). MDC is a recently identified member of the CC chemokine family. It is not closely related to other chemokines, sharing most similarity with thymus- and activation-regulated chemokine (TARC), which contains 37% identical amino acids. In addition, MDC gene is mapped to chromosome 16q13, the same position reported for the TARC gene. MDC has the four-cysteine motif and other highly conserved residues characteristic of CC chemokines, but it shares<35% identity with any of the known chemokines. Recombinant MDC was expressed in Chinese hamster ovary cells and purified by heparin-Sepharose chromatography. MDC is highly expressed in macrophages and in monocyte-derived dendritic cells, but not in monocytes, natural killer cells, or several cell lines of epithelial, endothelial, or fibroblast origin. High expression was also detected in normal thymus and less expression in lung and spleen. MDC is thus a unique member of the CC chemokine family that may play a fundamental role in the function of dendritic cells, natural killer cells, and monocytes.

7 Customer Q&As for Human CCL22/MDC ELISA Kit PicoKine®

Question

Q: can you suggest the dilution ratio of serum samples for detection of CCL22 in Human plasma? I am trying to measure a a number of analytes and it requires 100ul of diluted samples for each well. We have low serum quantitys so we like to dilute as much as possible.

Verified Customer

Verified customer

Asked: 2020-10-26

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 CCL22 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: if the enzyme conjugated CCL22 antibodies are mixed with the substrate, will that change the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the CCL22 antigen?

Verified Customer

Verified customer

Asked: 2020-03-20

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 optimal O.D. value for CCL22 ELISA kit? I performed your CCL22 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 CCL22 even though the O.D. values are not very high?

L. Thompson

Verified customer

Asked: 2019-10-10

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 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 CCL22 ELISA kit to have sensitivity of 1pg/ml, that means the minimum amount of CCL22 that can be declared/interpreted as positive by the above standard is 1pg/ml.

Question

Q: is it okay to use citrate plasma as samples in Human CCL22 Picokine® ELISA Kit (Catalog # EK0446)?

Verified Customer

Verified customer

Asked: 2019-07-29

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can bind metal ions from the functional domain of CCL22 causing degradation of its protein structure. CCL22 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 CCL22 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: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for quantification CCL22 using the EK0446 Human CCL22 Picokine® ELISA Kit?

S. Gonzalez

Verified customer

Asked: 2018-07-15

Answer

A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may alter 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 repetitive freeze-thaw cycles with the stored samples in order to limit protein degradation.

Asked: 2016-07-14

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.
