Form	Liquid or Lyophilized powder
Buffer	Liquid form: default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. Lyophilized powder form: the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution	Briefly centrifuged the vial prior to opening to bring the contents to the bottom. Reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL. It is recommended to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. The default final concentration of glycerol is 50%.
Storage	1. Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. 2. Avoid repeated freeze-thaw cycles. 3. Store working aliquots at 4°C for up to one week. 4. In general, protein in liquid form is stable for up to 6 months at -20°C/-80°C. Protein in lyophilized powder form is stable for up to 12 months at -20°C/-80°C.
Notes	Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Details

Target Function	Major immune regulatory cytokine that acts on many cells of the immune system where it has profound anti-inflammatory functions, limiting excessive tissue disruption caused by inflammation. Mechanistically, IL10 binds to its heterotetrameric receptor comprising IL10RA and IL10RB leading to JAK1 and STAT2-mediated phosphorylation of STAT3. In turn, STAT3 translocates to the nucleus where it drives expression of anti-inflammatory mediators. Targets antigen-presenting cells (APCs) such as macrophages and monocytes and inhibits their release of pro-inflammatory cytokines including granulocyte-macrophage colony-stimulating factor /GM-CSF, granulocyte colony-stimulating factor/G-CSF, IL-1 alpha, IL-1 beta, IL-6, IL-8 and TNF-alpha. Interferes also with antigen presentation by reducing the expression of MHC-class II and co-stimulatory molecules, thereby inhibiting their ability to induce T cell activation. In addition, controls the inflammatory response of macrophages by reprogramming essential metabolic pathways including mTOR signaling.
Subcellular Location	Secreted.
Protein Families	IL-10 family
Database References	KEGG: bta:281246 STRING: 9913.ENSBTAP00000008793 UniGene: Bt.4723

Gene Functions References

Studied expression of Interleukin 10 (IL-10) in blood and milk samples of 25 healthy and 25 mastitic cows. Found IL-10 expression to be significantly higher in the blood and milk samples of mastitic cows compared to the healthy ones. PMID: 28267404
This study seems to indicate that PGE2 in cattle does not produce an anti-inflammatory effect by increasing the synthesis of IL-10. PMID: 25286662
IL-10 mRNA expression increased on day 8 in the mononuclear leukocytes of pregnant cows. In a cell culture experiment, interferon-tau stimulated stimulated IL-10 mRNA expression in mononuclear leukocytes. PMID: 22052007
Bovine IL-10 potently inhibits the activation of human myeloid cells in response to toll like receptor activation. PMID: 21464967
Levels in milk are altered in the presence of bacteria. PMID: 15372997
Monocytes obtained from cows with subclinical infection with MAP had upregulated expression of IL-10 and SOCS-3, which may have attenuated the capacity of mononuclear phagocytes to initiate inflammatory and adaptive immune responses. PMID: 16111147

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.
