Target Details

Target Function Participates in at least several B-cell activation processes as well as of other cell types. It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. Positively regulates IL31RA expression in macrophages. Stimulates autophagy in dendritic cells by interfering with mTORC1 signaling and through the induction of RUFY4.
Subcellular Location Secreted.
Protein Families IL-4/IL-13 family

Gene Functions References

  1. immunoreactivities of inflammatory cytokines, such as interleukin (IL)-2, its receptor (IL-2R), IL-4 and its receptor (IL-4R) in the cervical and lumbar spinal cord of young adult and aged beagle dogs, were compared. PMID: 23605681
  2. In dogs with leishmaniasis, there was high expression of genes encoding IL-4 in blood leucocytes. The predominance of IL-4 gene expression in the blood of asymptomatic dogs may favour parasite replication. PMID: 21511273
  3. The anti-inflammatory and anabolic effects of regulated expression of IL-4 in chondrocyte-scaffolds under in vitro inflammatory conditions, were investigated. PMID: 21991344
  4. This study focuses on the co-expression of interleukin-4 (IL-4) and insulin-like-growth factor-1 (IGF-1), which specifically target inflammation and cartilage repair, respectively. PMID: 20188584
  5. These findings suggest that polyunsaturated fatty acids are able to influence proliferation of peripheral blood mononuclear cells in healthy and atopic dogs but do not seem to influence cytokine transcription. PMID: 20187917
  6. IL-4 expressed in canine articular chondrocytes is biologically active and suppresses inflammatory mediators in vitro. PMID: 18789870

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
