Recombinant Human IGFBP4 protein, His-tagged

• Cat.No.: IGFBP4-832H
• Product Overview: Recombinant Human IGFBP4 aa. (Asp22~Glu258 (Accession # P22692)) fused with N-terminal His tag was produced in E. coli cells.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: Asp22~Glu258
• Description: This gene is a member of the insulin-like growth factor binding protein (IGFBP) family and encodes a protein with an IGFBP domain and a thyroglobulin type-I domain. The protein binds both insulin-like growth factors (IGFs) I and II and circulates in the plasma in both glycosylated and non-glycosylated forms. Binding of this protein prolongs the half-life of the IGFs and alters their interaction with cell surface receptors.
• Form: Freeze-dried powder
• Molecular Mass: Predicted Molecular Mass: 27.5kDa
• Endotoxin: <1.0EU per 1µg (determined by the LAL method)
• Purity: > 95%
• Characteristic: The isoelectric point is 6.8.
• 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
