$3 is a major understimation, but I see your point. On the other hand, it is important to consider new technologies, and it would be a service to the scientific community to publish the exome somewhere, so other researchers would not have to spend their $3.

Assuming your gene is transcribed as mono-cistronic mRNA, take the oligodT primer as reverse primer. First isolate the total RNA from the tissue or cells and do the cDNA synthesis using oligodT primer followed by gene specific PCR with forward primer and oligodA primer from the cDNA pool. Sequence the PCR product to get to know the first stop codon in the ORF. Making the specific reverse primer from the sequence is then just matter of time. Hope this helps.

I searched the database only partial sequence is available, ie: for 160 residues only. The full length of the protein is around 570 residues. I designed forward primer and I have no clue to design reverse primer. Any help Thank you Syed
