a) The best vector to use determine receptor binding protein expression would have been one with a GFP gene (green flourescent protein) attached. State one (1) reason why including this gene would have made the experiment easier and whether you have inserted the receptor binding domain gene before or after the GFP gene.
b) You wish to determine the sucess pf your transformation by detecting the presence of receptor binding domian mRNA. Describe the key steps of the hybrdization technique you would use, clearly stating how you would design the probe to detect your receptor mRNA.

To investigate the functional and biochemical signatures of spike (S) protein upon engaging its receptor ACE2 in live cells, we first utilized a cell–cell fusion assay to obtain potentially cleaved spike protein products from syncytia . In this system, HEK293T cells transfected with plasmids encoding WT spike readily formed syncytia after coculturing with HEK293T cells expressing human and Vero E6-ACE2, as well as colorectal adenocarcinoma Caco-2 and lung adenocarcinoma Calu-3 cells expressing endogenous ACE2. We then collected these adherent syncytia and immunoblotted for cleaved spike species using a rabbit polyclonal antibody specifically detecting the S2 ectodomain through standard reducing Tris-glycine sodium dodecyl sulfate polyacrylamide gel electrophoresis. This experiment revealed that spike expression in HEK293T cells displayed full-length S and autocleaved S2…arrow_forward
