mh. the very cheapest and laziest way would be a ammonumsulfate precipitation. with this you would end up with the total immunoglobulines. but its dirty. you can then just determine total protein content. but you would also get non-Ig proteins in it. like beta2microglobuline. all globulines would be in the final mix.

better would be an electrophoresis. you could do it with SDS PAGE, or better native gel and scan the gel after staining with coomassie.

then you use densitrometry to determine the IG amount. but if you use SDS-PAGE, you need to select anything, heavy and light chains... bit challenging but possible.

or you do a standard electrophorsis such as the clinic labs are doing. this can be done in various ways. you get the gamma globuline fraction.

do you have an antiserum or antibody? or maybe you can get cross-reactive antibodies to chameloid. BD should have some. chameloid Igs are used in phage display... so there should be antibodies.
