Recombinant Cynomolgus IL-1 Rrp2 / IL-1 R6 Protein, His Tag, 100 µg

Background
The Interleukin 1 receptor family (IL-1 R) comprises at least eleven members including IL-1 RI (IL-1 R1), IL-1 RII (IL-1 R2), IL-1 RAcP (IL‑1 R3), ST2 (T1/IL-1 R4), IL-18 Ra (IL-1 Rrp/IL-1 R5), IL-1 Rrp2 (IL-1 RL2/IL-1 R6), IL-18 Rb (AcPL/IL-1 R7), IL-1RAPL‑1 (TIGIRR‑2/IL‑1 R8), and TIGIRR-1 (IL-1 R9).  All family members possess three immunoglobulin (Ig)-like domains in their extracellular region. Most members also have an intracellular TIR (Toll-like receptor/IL-1 receptor signaling) domain that is also conserved in the Toll-like receptor family. Related proteins, SIGIRR (single Ig domain-containing IL-1 R-related molecule) and IL-18BP, differ from the other members by having only one Ig domain.

Source
Recombinant Cynomolgus IL-1 Rrp2, His Tag (IL2-C52H5) is expressed from human 293 cells (HEK293). It contains AA Asp 20 - Arg 335 (Accession # EHH61702.1).
Predicted N-terminus: Asp 20

Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 37.9 kDa. The protein migrates as 50-66 kDa under reducing (R) condition (SDS-PAGE) due to Glycosylation.

Endotoxin
Less than 1.0 EU per μg by the LAL method.
 
Purity
>90% as determined by SDS-PAGE.

Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Reconstitution
Please see Certificate of Analysis for specific instructions.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

Storage
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
-20°C to -70°C for 12 months in lyophilized state;
-70^°C for 3 months under sterile conditions after reconstitution.
