Reactivity
Application examples
10 µg of total protein extracted freshly from mutant HEK293 cells with RIPA buffer and denatured at 65°C for 5 min were separated on 15% SDS-PAGE and blotted overnight to PVDF (pore size of 0.4 um), using wet transfer. Blot was blocked with 5% milk or 2 h at RT and then incubated in the primary antibody at a dilution of 1: 5 000 in a rotator for 2.5 h in 5% milk. The membrane was then placed in a clean container and rinsed 3 times for 5 min in TBS-T at RT with agitation. Blot was incubated in Agrisera matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, AS09 602) diluted to 1:20 000 in for 1 h at RT with agitation. The blot was washed as above and developed with Agrisera ECLSuperBright. Exposure time was 30 seconds.

HEK293 cells were transfected with the indicated plasmid (SARS-CoV-2 N myc tagged, PMID: 34799561, TBEV NS3-HA, PMID: 29321318, Rab5 mcherry, Addgene: 4920, GFP-HIS) using genejuice transfection reagent (EMD Millipore) according to the manufacturer’s instructions. After 24 hours of transfection, cells were fixed in 4% formaldehyde and permeabilized in PBS containing 0.5% Triton X-100 and 20 mM glycine. Then, cells were stained with the primary anti-HA epitope tag, rabbit polyclonal antibodies at a concentration of 1 μg/mL for 1 hour at room temperature. Followed by three washes in PBS. Cells were then stained using secondary antibodies, donkey antirabbit Alexa488 (1:500, Thermo Fisher Scientific, a21206 in PBS containing 2% BSA for 1h at RT. Nuclei were stained using DAPI (1 μg/mL). Images were acquired using a Leica SP8 Laser Scanning Confocal Microscope with a 63x oil objective (Leica) and Leica Application Suit X software (LAS X, Leica). Anti-NS3 antibodies are used as a control.
