Recombinant Human Calreticulin, His-tagged

• Cat.No.: CALR-906H
• Product Overview: Recombinant Human calreticulin encoding the human Calreticulin (Glu18P-Leu417P) with 6 His tag on the N-Terminus was expressed inE. Coli.This protein was purified by Ni-NTA column. MW=50KD.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 18-417 a.a.
• Description: Calreticulin is a multifunctional protein that binds Ca2+ ions (a second messenger molecule in signal transduction), rendering it inactive. The Ca2+ is bound with low affinity, but high capacity, and can be released on a signal (see inositol triphosphate). Calreticulin is located in storage compartments associated with the endoplasmic reticulum.
