Mouse Embryonic Stem Cell SILAC Kit 

SILAC kits and reagents for mouse embryonic stem cell proteomic analysis.

Stable isotope labeling of amino acids in cell culture (SILAC) produces mass-differentiated pairs of spectra that allow protein quantitation

The Thermo Scientific Pierce Mouse Embryonic Stem Cell SILAC Kit, Media and Reagents are specifically designed for analysis of protein expression by mass spectrometry using a method called stable isotope labeling with amino acids in cell culture (SILAC). The kit includes a complete set of specialized media, supplements and heavy and light isotopes of lysine for performing a complete experiment. In addition, individual components are offered, including the expansion DMEM and low-osmolarity DMEM (media), compatible serum and serum-substitute supplements and alternative lysine and arginine isotope pairs.

 

What is SILAC?

Stable isotope labeling with amino acids in cell culture (SILAC) is a powerful method to identify and quantify relative differential changes in complex protein samples. The SILAC Method uses in vivo metabolic incorporation of "heavy" 13C- or 15N-labeled amino acids into proteins followed by mass spectrometry (MS) analysis for accelerated comprehensive identification, characterization and quantitation of proteins.

Highlights of SILAC Products for Mouse Embryonic Stem Cells:

  • Optimized, specialized media – the Expansion DMEM and Low-Osmolarity DMEM are specifically designed and qualified for mouse embryonic stem cell propagation and SILAC protein expression profiling with mass spectrometry
  • High-quality supplements – the Stem Cell Screened Dialyzed FBS and Serum Substitute for Mouse Embryonic Stem Cells are tested to ensure that they do not promote stem cell differentiation; the Phenol Red-Free MEM Media for SILAC can be used with estrogen responsive cells such as the breast adenocarcinoma cell line MCF7, without inducing an artificial estrogen response
  • Flexible and compatible – media and the SILAC procedure are compatible with all standard mass spectrometry instrumentation
  • Multiplex capabilities – several alternative isotopes of arginine and lysine are available that allow for analysis of multiple growth conditions in each experiment. (For additional individual SILAC reagents and amino acid isotopes see related SILAC Product page).
  • Thousands of proteins – in vivo labeling with arginine and lysine isotopes using endogenous translational machinery enables expression analysis of the entire proteome; investigate any protein or group of proteins you choose

SILAC Applications:

  • Quantitative analysis of relative changes in protein abundance from different cell treatments
  • Quantitative analysis of proteins for which there are no antibodies available
  • Protein expression profiling of normal vs. disease cells
  • Identification and quantification of hundreds to thousands of proteins in a single experiment
Proteome analysis of GRP94 mouse embryonic stem cells using SILAC and muscle differentiation conditions. Proteome analysis of GRP94 -/- mouse embryonic stem cells using SILAC and muscle differentiation conditions.
A. Protein expression changes observed with SILAC between GRP94 -/- mouse embryonic stem cells under growth (13C6, 15N2-"heavy" lysine) versus muscle differentiation conditions ("light" lysine, 0.8% DMSO for six days).
B.
Proteins identified and quantified after analysis with a Thermo Scientific LTQ-FT Mass Spectrometers and Bioworks 3.3.1 Software, and MAPPFinder.
C.
Significantly regulated gene ontologies were observed in GRP94 -/- mouse embryonic stem cells under muscle differentiation conditions. These cells cannot differentiate into muscle without GRP94 function or insulin-like growth factor supplementation. The down regulation of nearly 30 ribosomal proteins during "frustrated" muscle differentiation indicates that protein translational machinery is being profoundly regulated.
