A method for increasing the percentage of mammalian offspring of either sex which comprises contacting a semen sample with an antibody specific for the spermatozoa determinative of one sex and separating said spermatozoa from spermatozoa determinative of the other sex, said antibody being bound to a non-porous magnetic bead support having a diameter of 0.1 to 2 microns.

Method for sex determination of mammalian offspring

An assay method is provided to easily and quickly detect the presence of organisms capable of being cultured, such as bacteria, characterized by antibody capture of the organism of interest by use of specialized magnetic beads, incubation of the captured cells to form colonies; removal of material from the colonies with a colony lift membrane; and detection of the colony material on the membrane sheet by use of labeled antibodies, PCR or nucleic acid probes.
