Optimizing high throughput antibody purification by using continuous chromatography media.

The ability to engineer monoclonal antibodies (mAbs) with high specificity made mAbs the fastest growing segment in the drug market. mAbs represent 8 of the top 20 selling drugs with combined sales of more than 57 billion US$ per year. The ability to purify large numbers of mAbs with sufficient yields for initial screening campaigns has direct impact on the timelines of a project.

Acute delivery of EphA4-Fc improves functional recovery after contusive spinal cord injury in rats.

Blocking the action of inhibitory molecules at sites of central nervous system injury has been proposed as a strategy to promote axonal regeneration and functional recovery. We have previously shown that genetic deletion or competitive antagonism of EphA4 receptor activity promotes axonal regeneration and functional recovery in a mouse model of lateral hemisection spinal cord injury. Here we have assessed the effect of blocking EphA4 activation using the competitive antagonist EphA4-Fc in a rat model of thoracic contusive spinal cord injury.
