SILAC-Mouse Diet: A New Silantes Proteomics Product
SILAC-mouse is a new in vivo proteomics approach (Ong et Mann 2006) permitting quantitative determination of protein patterns of mouse organs. The concept is similar to that of the well established SILAC-approach (Ong et al. 2002) aiming at the quantification of proteins in cell cultures. The workflow scheme of SILAC-mouse is shown below. In order to determine the protein status of mouse (A) with respect to mouse (B), tissues of mice (A) and (B), both of which were fed a diet containing only unlabelled (12C6) lysine, are each mixed with tissue of mouse (R) which was fed a diet in which 12C6 lysine has been replaced by 13C6-lysine. Silantes, in cooperation with the group of Prof. Matthias Mann, Max-Planck-Institute of Biochemistry, has developed a kit for performing the SILAC-mouse approach (Krüger et al.2008). The Lys(6)-SILAC-Mouse Diet Kit consists of two feeds:
A feed (from Harlan) which is composed of a conventional amino acid-based diet containing 12C6-lysine (light feed). This diet is used for feeding mice (A) and (B);
The same feed as above but 12C6-lysine is replaced by 13C6-lysine (heavy feed). This diet is used for feeding the reference mouse (R). Alternatively, the Lys(8)-SILAC-Mouse Diet Kit is available in which 13C6-lysine is replaced by 13C6,15N2-lysine yielding an 8 Da molecular weight shift of the proteolytically cleaved peptides.
