Application examples

Application examples Application example 

western blot using anti-VENUS polyclonal antibodies

200 ng mVenus YFP protein (1); 100 ng mVenus YFP protein (2) ; 49 ng mVenus YFP protein (3) ; 24 ng mVenus YFP protein (4) ; 12 ng mVenus YFP protein (5)
MW markers: BenchMark™ Pre-stained Protein Ladder (10748010)
>0.200 – 0.012 µg of total protein from a pure stock of mVenus YFP protein in 1x SIGMAFAST EDTA-free Protease Inhibitor (S8830-2TAB) and denatured with 1x reducing Laemmli SDS buffer at 90°C for 10 min, and insoluble material pelleted at 20,000 xg for 15 min. Samples were run to separation on a 4-12% SDS-PAGE gel and blotted 7 mins to PVDF using ThermoFisher iBlot high voltage Protocol 3. Blot was blocked with 7.5 % milk in TBS-T for 20mins/RT with agitation. Blot was incubated in the primary antibody (i.e. Rabbit anti-Venus IgG) at a dilution of 1:10 000 with 7.5 % milk in TBS-T ON/4°C with agitation. The antibody solution was decanted and the blot was rinsed briefly three times, then washed once for 15 min and 3 times for 5 min in TBS-T at RT with agitation. Blot was blocked with 7.5 % milk in TBS-T for 20mins/RT. Blot was then incubated in Agrisera matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:10 000 in TBS-T for 2.5h/RT with agitation. The blot was washed as above, then as above with TBS, and developed for 5 min with chemiluminescent detection reagent, according to manufature's instruction. 
Exposure time was approximately 3 seconds.

Collection of antibodies to GFP proteins


Background Green fluorescent protein (Venus) from Aequorea victoria (Jellyfish), can be mutated to emit at different wavelengths such as blue for BFP (when Tyr-66 is replaced by His), cyan for CFP (when Tyr-66 is replaced by Trp), and yellow for YFP (when THR-203 is replaced by Tyr). It is an energy-transfer acceptor. Its role is to transduce the blue chemiluminescence of the protein aequorin into green fluorescent light by energy transfer.
