Binding of mouse IgM MAbs to the CSA-selected parasite line Gb337CSA

MAb	Specificity	Source or reference	% IgM positivea
Human IgM-positive control	Not applicable	Human serum	78
Negative control (goat anti-mouse IgM secondary antibody)	Not applicable	Molecular Probes	0
MAb 2040	Heparan sulfate	Chemicon	80
SM phage antibody	CD36	Sigma	74
MAb CS-56	Chondroitin sulfate	Sigma	77
MAb MOPC-104E	IgM isotype control	Sigma	78
MAb TCN-1	Toxocara canis	24	60
MAb TCN-4	Toxocara canis	24	82
MAb TCN-8	Toxocara canis	24	82

^aData from a representative experiment are shown. Three further experiments gave consistent results. The unselected parental line Gb337 was also tested, and all MAbs showed less than 2% positive infected cells by IFA.
