| Formulation |
IL1F5 was lyophilized after extensive dialysis against 20mM Phosphate buffer, pH7.4. |
| Solubility |
It is recommended to quick spin followed by reconstitution of IL1F5 in PBS to a concentration no less than 100 ug/ml, which can then be further diluted to other aqueous solutions. |
| Purity |
Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
| Description |
IL1F5 Human Recombinant produced in E.Coli is a single, non-glycosylated, Polypeptide chain containing 155 amino acids and having a molecular mass of 17kDa.The IL1F5 is purified by proprietary chromatographic techniques. |
| Protein Background |
Human interleukin family 1, member 5 (IL-1F5 / FIL1-delta) belongs to the interleukin 1 cytokine family. IL1F5 is expressed by a variety of cells including monocytes, Bcells, dendritic cells/Langerhans cells, keratinocytes,and gastric fundus Parietal and Chief cells. IL1F5 is an antagonist of IL1F9; however IL1F5 activity related to receptor binding remains unclear. Human and mouse IL1F5 share 90% amino acid sequence identity. |
| Expression host |
Escherichia Coli. |
| Synonyms |
Interleukin-36 receptor antagonist protein, FIL1 delta, IL-1-related protein 3, IL-1RP3, Interleukin-1 HY1, IL-1HY1, Interleukin-1 delta, IL-1 delta, Interleukin-1 family member 5, IL-1F5, Interleukin-1 receptor antagonist homolog 1, IL-1ra homolog 1, Interleukin-1-like protein 1, IL-1L1, IL36RN, FIL1D, IL1F5, IL1HY1, IL1L1, IL1RP3, FIL1, PSORP, IL36RA, FIL1(DELTA). |
| Reagent Appearance |
Sterile Filtered White lyophilized (freeze-dried) powder. |
| Stability |
Lyophilized IL1F5 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL1F5 should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles. |
| Amino acid sequence |
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Val-Leu-Ser-Gly. |
| Biological Activity |
As measured by its binding ability in a functional ELISA, immobilized IL1F5 at 1 ug/ml (100 ul/well) can bind rHuIL-1 Rrp2/Fc Chimera with a linear range of 0.15- 5 ug/ml. |
