The invention provides methods and compositions for the rapid and sensitive detection of post-translationally modified proteins, and particularly of those with post-translational glycosylations. Diphosphinoarenes may be used as ligands for metal catalysts, as solvent extractants for certain metals, and as flame retardants in polyester and polyurethane applications. The anti-splatter device protects a user from splatters produced while cooking and also allows for easy manipulation of food using a utensil through the aperture. A plurality of printhead modules is positioned on the chassis. A PLMN ID index is generated to indicate an association between the PLMN ID associated with the SGSN and one of the PLMN IDs of the set. The locating pin and the retention clip allow alignment of the front end module with the body structure and the retention clip secures the two assemblies in place which allows alignment of fastener holes.
