Application Details

Application Notes: Bioimaging
1. Seed the cells in appropriate culture medium at ~10,000 cells per well in an 96-well Imaging Plate and culture overnight.
2. Remove the culture medium from the wells, and fix the cells by adding 100 myl of Fixation Buffer to each well. Incubate for 10 minutes at room temperature (RT).
3. Remove the fixative from the wells, and permeabilize the cells using either 90% methanol, or Triton™ X-100: a. Add 100 myl of -20°C 90% methanol to each well and incubate for 5 minutes at RT. OR b. Add 100 myl of 0.1% Triton™ X-100 to each well and incubate for 5 minutes at RT.
4. Remove the permeabilization buffer, and wash the wells twice with 100 myl of 1× PBS.
5. Remove the PBS, and block the cells by adding 100 myl of to each well. Incubate for 30 minutes at RT.
6. Remove the blocking buffer and add 50 myl of the optimally titrated primary antibody (diluted in Stain Buffer) to each well, and incubate for 1 hour at RT.
7. Remove the primary antibody, and wash the wells three times with 100 myl of 1× PBS.
8. Remove the PBS, and add the second step reagent at its optimally titrated concentration in 50 myl to each well, and incubate in the dark for 1 hour at RT.
9. Remove the second step reagent, and wash the wells three times with 100 myl of 1× PBS.
10. Remove the PBS, and counter-stain the nuclei by adding 200 myl per well of 2 myg/ml Hoechst 33342 in 1× PBS to each well at least 15 minutes before imaging.
11. View and analyze the cells on an appropriate imaging instrument.

Background: Growth-factor Receptor-Bound Protein 2 (GRB2) was isolated by using the EGF receptor C-terminus as a probe in the screening of lambdagt11 expression libraries. This 24 kDa GRB2 protein is ubiquitously expressed and consists of one SH2 domain flanked by two SH3 domains. Its ability to bind proteins through these domains has prompted much investigation of its role as an adaptor protein. Sos, a Ras GDP/GTP exchange protein, is constitutively bound to the SH3 domain of GRB2. Following growth factor stimulation, receptor tyrosine kinases autophosphorylate, creating a binding site for the GRB2 SH2 domain. Alternatively, GRB2 interacts with the receptor-bound active Shc protein.Through these interactions, the GRB2/Sos complex is translocated to the membrane where Sos activates membrane-bound Ras to initiate the Ras signaling pathway. Other proteins that similarly interact with GRB2 include Cbl, PTP1D, and Dynamin. However,the mechanisms through which these associations impact cellular responses remain to be discovered.
