There are two avaliable antibodies to HA tag. Monoclonal, called 12CA5
which I believe Bohringer sells, as well as the rabbit polyclonal called
HA.11 sold by BABCO Antibodies from California. I have nothing with these
companies other than bying their products.

You should tag it at the 5' end since you probably don't want it to
interfere with your DNA binding.

You are going to be able to find the exact sequence in any reference in
which the HA tag has been used, what will allow you to synthetize the
oligonucleotides  and stick them to your cDNA.

Good luck!
