meso-1,2-Bis(methylazo)-1,2-diphenylethane

meso-1,2-bis(methylazo)-1,2-diphenylethane.

The title compound, meso-1,2-bis(methyldiazenyl)-1,2-diphenylethane, C16H18N4, is arranged in a disordered manner around an inversion point. The N-N atom distances in the azo group of 1.192 (8) and 1.195 (8) A, and the C-C atom distances in the ethylene moiety at 1.512 (8) and 1.503 (8) A in the two models [refined to 51.7 (6) and 48.3 (6)% occupancies] were not significantly different.

+ 12 or trisomy 12

Phenotype/cell stem origin virgin CD5+ recirculating B-cell; the classical CLL phenotype is CD5+, CD23+, CD22-, CD79a-, FMC7-, sIg weak; trisomy 12 is more often observed in CLL with morphologically and immunologically atypical cells, displaying CD5 negativity or FMC7 positivity and strong surface immunoglobulin staining; trisomy 12 is present in proliferating cells and seems to be associated w...

The archetypes The era of modern antibody therapy begins with Rodney Porter’s Nobel Prize-winning report on the basic structure of the immunoglobulin molecule. Using papain for digestion of a 7s rabbit antibody preparation, he obtained two almost identical antigen-binding fragments (Fab) that blocked antigen precipitation by the parent antibody while a third, easily crystallizable fragment (Fc)...
