I got a reply from Mr. Joel Nott who was working in Iowa
State University Protein Facility. He suggested me to
ask your group to sort out my problem.
I am presently studying for a Doctorate in the construction
of specialized antibodies for the treatment of Leukemia
Cancer.
At present I am having difficulties producing a peptide bond
between the carboxyl group of Polyhistidine and the amino
group of Cystiene. Any information or suggestions you can
offer will be much appreciated, as will any information
sources you can suggest that could aid me in this
experiment.
Yours faithfully,
