- Washing buffer (neutral PBS or TBS).
- Preparation of 0.01M TBS: Add 1.2g Tris, 8.5g NaCl; 450μl of purified acetic acid or 700μl of concentrated hydrochloric acid to 1000ml H2
- Preparation of 0.01 M PBS: Add 8.5g sodium chloride, 1.4g Na O and adjust pH to 7.2-7.
Typical Data Obtained from Human CCL22/MDC PicoKine™ ELISA Kit
(TMB reaction incubate at 37°C for 20-25min)
Intra/Inter Assay Precision
|Intra-Assay Precision||Inter-Assay Precision|
Three samples with differing target protein concentrations were assayed using four different lots to measure the CV% lot to lot variance.
To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.
|Lots||Lot1 (pg/ml)||Lot2 (pg/ml)||Lot3 (pg/ml)||Lot4 (pg/ml)||Mean (pg/ml)||Standard Deviation||CV (%)|
*The typical data is obtained from Boster's internal QC result and for reference only. It may differ from the lab test results of the end users. It is more important that the user's lab test results reflect the same linearity demonstrated in the typical data than achieving exactly the same O.D. values.
Protein Target Info (Source: Uniprot.org)
|Protein Name||C-C motif chemokine 22|
|Tissue Specificity||Highly expressed in macrophage and in monocyte-derived dendritic cells, and thymus. Also found in lymph node, appendix, activated monocytes, resting and activated macrophages. Lower expression in lung and spleen. Very weak expression in small intestine. In lymph node expressed in a mature subset of Langerhans' cells (CD1a+ and CD83+). Expressed in Langerhans' cell histiocytosis but not in dermatopathic lymphadenopathy. Expressed in atopic dermatitis, allergic contact dermatitis skin, and psoriasis, in both the epidermis and dermis. .|

*if product is indicated to react with multiple species, protein info is based on the human gene.
|Protein Function||May play a role in the trafficking of activated/effector T-lymphocytes to inflammatory sites and other aspects of activated T-lymphocyte physiology. Chemotactic for monocytes, dendritic cells and natural killer cells. Mild chemoattractant for primary activated T-lymphocytes and a potent chemoattractant for chronically activated T-lymphocytes but has no chemoattractant activity for neutrophils, eosinophils, and resting T-lymphocytes. Binds to CCR4. Processed forms MDC(3-69), MDC(5-69) and MDC(7-69) seem not be active.|
|Background||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.|
