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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°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
5-10 business days
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

This Recombinant Human CCL4 protein is an essential research tool for investigators in the field of immunology. This C-C motif chemokine 4, also known as CCL4, LAG1, MIP1B, and SCYA4, is expressed in E. coli, featuring the 24-92aa expression region of the full-length mature protein. The tag-free protein is supplied as a lyophilized powder, allowing for easy reconstitution with sterile water or buffer to facilitate a wide range of experimental applications.

Quality and performance are paramount for us, and our Recombinant Human CCL4 protein exhibits a purity of >96% as determined by SDS-PAGE and HPLC analysis. In addition, endotoxin levels are maintained below 1.0 EU/µg, as assessed by the LAL method. The protein demonstrates full biological activity in a chemotaxis bioassay using human peripheral blood monocytes, with an effective concentration range of 5.0-20 ng/ml.

Target Background

Monokine with inflammatory and chemokinetic properties. Binds to CCR5. One of the major HIV-suppressive factors produced by CD8+ T-cells. Recombinant MIP-1-beta induces a dose-dependent inhibition of different strains of HIV-1, HIV-2, and simian immunodeficiency virus (SIV). The processed form MIP-1-beta(3-69) retains the abilities to induce down-modulation of surface expression of the chemokine receptor CCR5 and to inhibit the CCR5-mediated entry of HIV-1 in T-cells. MIP-1-beta(3-69) is also a ligand for CCR1 and CCR2 isoform B.

  1. identified 13 ADCC-activated genes. Six gene expression assays including 8 of the 13 genes (CCL3, CCL4/CCL4L1/CCL4L2, CD160, IFNG, NR4A3 and XCL1/XCL2) were analyzed in 127 kidney biopsies PMID: 25449536
  2. PCR results show that lower copy numbers of CCL4L1 are observed in the Caucasian population nd higher copy numbers are observed in the Black population of South Africa. PMID: 24727646
  3. CCL4L1 allele frequency is higher in severe psoriasis, whereas CCL4L2 is more frequent in patients with a milder disease. PMID: 21614014
  4. multiple copies of CCL3L1 and CCL4L1 present in a single diploid genome are the result of segmental duplication at chromosome 17q12 PMID: 15028295
