further , this method yielded fairly reproducible results and allowed a crude estimate of the force involved in the binding of glutaraldehyde-treated sheep red cells ( gsrc ) or immunoglobulin-coated sheep red cells ( igsrc ) by rat macrophages ( an average force of 0.8 x 10 ( -7 ) newton was needed to separate 50 % of bound igsrc from macrophages ) .
