Although protein A or protein G purified total polyclonal IgG antibody can be good enough for some research applications, it may not be suitable in many other situations, probably due to low detection sensitivity or due to unacceptable background. In many cases, further purification and fractionation of the antigen specific antibodies from the total IgG antibodies can increase detection sensitivity and reduce undesirable background. This can be achieved by purifying with antigen conjugated resin.
Sino Biological has developed in house expertise in conjugating proteins and antigens to agarose resin, and has gained sufficient hands-on experience in purifying high quality antigen specific polyclonal antibodies. Our services have been highly reliable and cost-attractive to customers.
