In this group of experiments, we are aiming to test whether or not our receptor proteins localize to the cell membrane. To do that, we will have HEK293 cells express LilrB2 and PirB. We will test for membrane localization of the receptors through immunofluorescence. We will use primary antibodies that will bind to LilrB2 and and PirB and secondary antibodies conjugated to fluorophores that will bind to the primary antibodies.
In this group of experiments, we are aiming to test the affinity of our receptors, LilrB2 and PirB to beta-amyloid oligomers. To do that, we will have HEK293 cells express LilrB2 and PirB fused with YFP. We will then apply biotinylated beta-amyloid oligomers to the cells expression the LilrB2 and PirB fusions. To test for binding, we are going to use the biotin-binding protein streptavidin covalently bonded to a fluorophore. We will look for co-localization of the fluorescent protein and the beta-amyloid.
In this experiment, we want to want to compare the levels of endogenous cofilin and cofilin-eYFP expressed under an inducible promoter with different levels of dox induction. This will allow us to determine what level of expression of cofilin would lead to the best signal:noise ratio of binding of exogenous cofilin. We are planning to transfect HEK293 with cofilin-eYFP under a TRE promoter and induce with varying levels of dox. We will then preform a Western blot with an anti-cofilin primary antibody and compare band sizes to test for the relative amounts of endogenous cofilin and exogenous cofilin-eYFP in the cells.
In this experiment, we want to test for the recruitment of our engineered cofilin to the activated receptor proteins. To do this, we will transfect HEK293 cells with
How much TEV Protease we need in the system? - indicated by levels of dox
looking for biggest difference in transfer curve between w/ AB and without AB
two different ladders - dox and AB
