Our projects require the testing of various inflammatory stimuli or agonists on peritoneal macrophages from mice that are either drug-treated or untreated. To confirm or test our hypotheses on what targets may have been modulated upon inflammatory stimuli and drug treatment, we utilize best practice western blot techniques to analyze and measure the protein/target of interest in our experiments.

Experimental Design and Results Summary

Applications

Western Blot

Sample

Mouse peritoneal macrophages

Primary Incubation

1/10000 of Ab in 5% milk in TBST, overnight, 4 deg C

Blocking Agent

Non-fat dry milk proteins in TBS

Secondary Incubation

1/10000 of HRP-Ab in 5% milk in TBST, 1 hour, room temperature

Tertiary Incubation

None

Detection

X-Ray development using ECL and photofilm

Results Summary

The peritoneal macrophages were sorted using flow cytometry and the drug's inherent fluorescent signature. See - https://www.ncbi.nlm.nih.gov/pubmed/26109497. Post-sorting, the cells were plated for 24-48 hours before the agonists or inflammatory stimuli were applied. 8-24 hours post stimulus, cells were collected and lysed, measure for protein concentration and best practice western blot techniques were used as discussed above. As seen in the figure, the repeatable band production of b-actin in three different mice samples was easily verified suggesting equivalent protein loading in our gel.
