Porcine IL 1RA Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant IL 1RA based upon sequence from Porcine
Host: QP10698 protein expressed in E. Coli.
Available Tags: Untagged
Protein Construction: A cDNA sequence encoding the sequence of IL 1RA was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Application Notes
Recommended Reconstitution Instructions: It is recommended to reconstitute the lyophilized IL 1RA in sterile distilled H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Bioactivity Data: The ED50 as determined by inhibiting IL-1a-dependent proliferation of murine D10S cells is less than 50 ng/ml, corresponding to a specific activity of > 2.0 Ã 104 IU/mg in the presence of 75 pg/ml rPoIL-1a.
Monomer or Dimer: Dimer
Amino Acid Sequence: HPLGKRPCRM QAFRIWDVNQ KTFYLRNNQL VAGYLQGPNT KLEEKIDVVP VEPHFVFLGI HGGKLCLSCV KSGDEMKLQL DAVNITDLRK NSEQDKRFTF IRSDSGPTTS FESAACPGWF LCTALEADQP VGLTNTPKAA VKVTKFYFQQ DQ
Purity: Greater than 97.0% as determined by:(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Endotoxin Levels: < 1.0 EU per ug protein as determined by the LAL method.
Buffer: The IL 1RA was lyophilized from a 0.2µm filtered concentrated solution in 1ÃPBS, pH 7.4, containing 1mM DTT.
Storage Conditions: Lyophilized IL 1RA although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL 1RA should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
