Form Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Condition Store at -20°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Q&A and Customer Reviews

 Q&A
Q:

Do you happen to have LAL testing done on your CCL8 protein, expressed in Yeast, catalog number CSB-EP004802HU ? We are interested in using this on cells, but we are worried about endotoxin levels. If not, is that something that your company is easily able to run and find out?

A:
Very nice to receive your inquiry. If you would perform cell relevant experiment, we could provide Endotoxin Removal Service and Aseptic Manufacture Processing free of charge. The details are as below.
Please kindly remark "Endotoxin Removal Service & Aseptic Manufacture Processing" in your PO.
Endotoxin Removal Service
a.If customer plans to use a protein in cell culture, please check with us if it has been endotoxin tested and if it is suitable for this purpose.
b.If customer has requirement for endotoxin level, please remark this information when placing the order and we could offer endotoxin removal service free of charge.
c.We use conjugated PMB affinity filler adsorption to remove endotoxin and guarantee endotoxin level within 0.1ng / ug (1EU / ug).
d.Generally, the delivery time will be extended for 2-3 working days.
e.Endotoxin removal result will be shown in COA as follows “<1.0 EU per 1μg of the protein by the LAL method.”
Aseptic Manufacture Processing
a.If customer plans to use a protein in cell culture, please check with them if aseptic manufacture processing is required. If customer has demand for aseptic manufacture processing, then please remark this
information when placing the order.
b.We could offer aseptic manufacture processing service free of charge.
c.The delivery time won’t be extended.
d.We've performed Aseptic processing for liquid protein, before lyophilization, but there may exist contamination during lyophilization process, so we can't say bacteria free for the whole process.
e.Aseptic manufacture processing will be shown in both of datasheet & COA as follows “0.2 μm sterile filtered 20 mM Tris-HCl, 0.5 M NaCl, pH 8.0, 50% glycerol”.

Target Data

Function Chemotactic factor that attracts monocytes, lymphocytes, basophils and eosinophils. May play a role in neoplasia and inflammatory host responses. This protein can bind heparin. The processed form MCP-2(6-76) does not show monocyte chemotactic activity, but inhibits the chemotactic effect most predominantly of CCL7, and also of CCL2 and CCL5 and CCL8.

  6. Authors show that the previously observed downregulation of hsa-miR-92a and upregulation of CCL8 during human cytomegalovirus latent infection of myeloid cells are intimately linked via the latency-associated expression of cytomegalovirus UL111A. PMID: 25253336
  7. CCL8 is an antimicrobial protein with bacteriocidal activity against E. coli. PMID: 12949249
  8. Results indicate that the induction of MCP-2/CCL8 by mycobacteria is dependent on the activation of TLR2/PI3K/Akt signaling pathway. PMID: 23418602
  9. Macrophage Colony Stimulating Factor and Monocyte Chemoattractant Protein are elevated in sera of intrinsic asthmatics compared to normal controls. PMID: 21945122
  10. genetic polymorphhism is associated with a risk of death for non-small cell lung cancer in Chinese PMID: 21514686

  12. CCL8/MCP-2 is a target for mir-146a in HIV-1 infected microglia, as overexpression of mir-146a prevented HIV-induced secretion of MCP-2 chemokine PMID: 20181935
  13. TRAIL pretreatment of endothelial cells down-modulated mRNA steady-state levels of several TNF-alpha-induced chemokines, and it abrogated the TNF-alpha-mediated up-regulation of CCL8 and CXCL10, modulating leukocyte/endothelial cell adhesion PMID: 15644410

  19. These data indicate that optimal induction and delivery of MCP-2/CCL8 is counteracted by converting this chemokine into a receptor antagonist, thereby losing its anti-tumoral potential. PMID: 19224633
  20. CCL8/MCP rs1133763 SNP, or other variants in linkage disequilibrium with this variant, likely do not influence the susceptibility to AD or FTLD in Caucasians. PMID: 19415413
