Bon Opus has been very responsive in helping us generate a series of customized polyclonal antibodies that target a cell surface transmembrane protein of interest. The technical specialists from the company worked closely with us to design the antigen sequence and were able to communicate with us in a timely manner. When technical difficulties occurred during the process, the team came up with an alternative solution immediately and offered the same price. The company worked efficiently and delivered the products at the desired quality and quantity in approximately 4.5 months. Overall, it has been a very pleasant experience working with Bon Opus.
