WebRéférence: 2943542050. Thermo Scientific CaptureSelect IgE Affinity Matrix has been designed specifically for the purification of human IgE (immunoglobuline E) from recombinant and plasma sources. CaptureSelect products contain affinity ligands based on recombinant single-domain antibody fragments (VHH) created by a proprietary technology. WebFisher Matrix Confidence Bounds. This section presents an overview of the theory on obtaining approximate confidence bounds on suspended (multiply censored) data. The methodology used is the so-called Fisher matrix bounds (FM), described in Nelson [30] and Lloyd and Lipow [24]. These bounds are employed in most other commercial statistical ...
