Recombinant Rat Il18 protein, His-tagged

• Cat.No.: Il18-877R
• Product Overview: Recombinant Rat Il18 aa. (His37~Ser194 (Accession # P97636)) fused with N-terminal His tag was produced in E. coli cells.

Specification

• Species: Rat
• Source: E.coli
• Tag: His
• Protein Length: His37~Ser194
• Description: A pro-inflammatory cytokine; acts as a modulator of immune functions.
• Form: Freeze-dried powder
• Molecular Mass: 20 kDa as determined by SDS-PAGE reducing conditions.
• Endotoxin: <1.0EU per 1µg (determined by the LAL method)
• Purity: > 95%
• Characteristic: The isoelectric point is 6.2.
• Applications: SDS-PAGE; WB; ELISA; IP
• Stability: The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
• Storage: Avoid repeated freeze/thaw cycles. Store at 2-8°C for one month. Aliquot and store at -80°C for 12 months.
• Storage buffer: Supplied as lyophilized form in PBS, pH7.4, containing 5% trehalose, 0.01% sarcosyl
• Reconstitution: Reconstitute in sterile PBS, pH7.2-pH7.4
