产品说明

一般描述

Fast and reproducible extraction of subcellular proteomes from mammalian cells
ProteoExtract<TMSYMBOL></TMSYMBOL> Subcellular Proteome Extraction Kit (S-PEK) is designed for fast and reproducible extraction of subcellular proteomes from adherent and suspension-grown mammalian cells. The S-PEK takes advantage of the different solubilities of certain subcellular compartments in the four selected reagents. In the case of adherent cells, the procedure is performed directly in the tissue culture dish without the need for cell removal. Cells or the parts of the cells remain attached to the plate during sequential extraction of subcellular compartments, until the appropriate extraction reagent is used. Thus, the early destruction of the cellular structure by enzymatic or mechanical detachment of cells from the tissue culture plate and any mixing of different subcellular compartments is prevented. For suspension-grown cells, extraction starts with gentle sedimentation and washing of the cells. The stepwise extraction delivers four distinct protein fractions from one sample:

  • Cytosolic fraction (F1)
  • Membrane/organelle protein fraction (F2)
  • Nucleic protein fraction (F3)
  • Cytoskeletal fraction (F4)
Proteins are obtained in the native state making the S-PEK suitable for many downstream applications such as 1D and 2D gel electrophoresis, immunoblotting, enzyme activity assays, and protein microarrays.
Sample size: 3-5x106 or 25-50 mg tissue.

Appropriate samples types include:

  • Adherent tissue culture cells
  • Suspension-grown tissue culture cells
  • Frozen cell pellets
  • Fragmented tissue

Kit Components Needed for One Extraction
The volume of each component required for one subcellular extraction depends on the amount of starting material and is shown in the table below. <div class="Bio_doc_image">

*Tested on rat liver and bovine liver tissue.
</div>The following table lists the amount of extraction buffer needed for extracting proteins from cells grown in various size tissue culture flasks and dishes. As guideline to estimate the amount of starting material please refer to the table above for a listing of expected protein yields obtained from selected cell types following S-PEK extraction.<div class="Bio_doc_image">Table 3: Buffer Volumes Required for S-PEK Extraction Based on Flask/Dish Size
