Abstract: Human leukocyte antigen (HLA) coated magnetic bead compositions, panels and methods of use thereof. A method of isolating HLA-specific antibodies including: contacting the composition of the disclosure with a liquid sample to specifically bind antibodies present in the liquid sample to HLA immobilized on magnetic beads; separating magnetic beads having antibodies bound to HLA of the magnetic beads from the liquid sample; and isolating the bound antibodies.

Abstract: There is disclosed a method of making transformer core laminates with bent corners from magnetic strip material having a predetermined thickness and power loss in the manufacture of a low-stress polyhedral core for a power transformer. The method includes mechanically bending corners in each laminate about predetermined bending lines while limiting the zone in each corner where the laminate is subject to plastic deformation to <5 times laminate thickness so that the specific power loss in the transformer core will equal that of the magnetic strip material except within the distance from the bending lines, where the power loss is higher due to plastic deformation of the magnetic strip material.
