Descripción

General description

Lys, Arg ¹³C and ¹⁵N metabolically labeled recombinant human protein fragment

Application

Internal standard in MS-based quantitative proteomics

Physical form

Heavy proteins are provided in solution of 1M Urea PBS, pH 7.4

Preparation Note

The protein solution should be gently mixed before use. Optimal concentrations and conditions for each application should be determined by the user.

Analysis Note

Isotopic Label Incorporation

The SILuPrEST standards are produced using metabolic labeling with heavy isotope labeled (15N, 13C) Lysine and Arginine residues, with greater than 99% isotopic label incorporation.

A purification and quantification tag (QTag) consisting of a hexahistidine (His6) sequence followed by an Albumin Binding Protein (ABP) domain derived from Streptococcal Protein G.

All SILuPrESTs contain an N-terminal His6ABP fusion tag, used for accurate determination of concentration. The fusion tag sequence is:
