Product Name :
HA-tag polyclonal antibody Background :
Human influenza hemagglutinin (HA) is a surface glycoprotein required for the infectivity of the human virus. The HA tag is derived from the HA molecule corresponding to amino acids 98-106 has been extensively used as a general epitope tag in expression vectors. Many recombinant proteins have been engineered to express the HA tag, which does not appear to interfere with the bioactivity or the biodistribution of the recombinant protein. This tag facilitates the detection, isolation, and purification of the proteins. Product :

  Western blot (WB) analysis of HA-tag polyclonal antibody at 1:5000 dillution Lane1:HEK293T whole cell lysate ,untransfected (40μg) Lane2:HEK293T whole cell lysate , transfected with pRK5-(HA)2-RhoA(35μg)
• 
  IF image of AP0005 stained HEK293T cells, transfected with pcDNA3.1-p62 #PPL00549-2b. The cells were 4% paraformaldehyde fixed (20 min) and then incubated in 10% normal goat serum for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody HA-tag pAb #AP0005(1:200) at 5µg/ml overnight at +4°C. The secondary antibody (Green) wasGoat anti-Rabbit IgG (H+L) -FITC#BS10950 used at a 1/1000 dilution for 1h. Hoechst33342 #BD5011 was used to stain the cell nuclei (blue).

Describe :

Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. This mechanism is useful when non-specific binding is an issue, for example, in Western blotting (WB) and Immunohistochemistry (IHC). By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific; Specific binding will be absent from the western blot or IHC performed with the neutralized antibody.
