Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA710192) at 1/5,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Streptavidin-HRP Secondary Antibody at 1/20,000 dilution was used for 1 hour at room temperature.

293T cells, transfected with Myc-tagged empty control, Histone H3.1 (C-terminal) or ACAT2 (N-terminal) expression vector, respectively, were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Alpaca anti-His tag, AlpSdAbs® VHH(Biotin) antibody (HA710192) at 1/100 dilution in 1% BSA in PBST overnight at 4 ℃. Streptavidin-FITC was used as the secondary antibody at 1/1,000 dilution. Nuclear DNA was labelled in blue with DAPI.
HA710192_3.jpg Fig3: Advantages of using an Alpaca Recombinant Secondary
1. Smaller size
Nanobodies are 1/10 the size of a traditional antibody (~15 kDa unconjugated). This means that the nanobody can penetrate tissue faster and deeper than other antibodies.
2. Easier to use
Due to their simple structure, nanobodies also have the advantage of increased stability and ease of use.
3. Easier production
When compared to a more traditional antibody, nanobodies are easier to develop and produce in the lab than monoclonal or polyclonal antibodies.
4. More consistent
Since nanobodies are recombinantly produced from clonal DNA, you are guaranteed the same product every time. Comparatively, polyclonal antibodies are produced in live animals and have a very low lot-to-lot consistency while monoclonal antibodies can suffer from drift.
5. Higher Affinity
Nanobodies benefit from consistently high binding affinity values.
