Comprehensive two-dimensional gas chromatography mass spectrometry (GC×GC-MS) is a powerful tool for the analysis of complex mixtures, and it ideally suited to discovery studies where entire sample potentially interest. Unfortunately, when unit resolution spectrometers are used, many detected compounds have spectra that do not match well with libraries. This could be due compound being in libra...

Glycoprotein C (gC) of both herpes simplex virus type 1 (HSV-1) and HSV-2 interacts with complement C3b and protects the virus from complement-mediated neutralization. To study the mechanism by which gC modulates complement activation, we expressed both gC-1 and gC-2 in a baculovirus expression system. Baculovirus recombinants containing gC genes spanning the entire gC-1 sequence (gC-1-TMR) or ...

Comprehensive two-dimensional gas chromatography (GC x GC) offers new opportunities to develop relationships between molecular structure and retentions in the two dimensional (2D) separation space defined by the GC x GC retention in each dimension. Whereas single dimension GC provides only one retention property for a solute, and hence the specific relationship between retention and chemical pr...

Atrial (ANP) and C-type (CNP) natriuretic peptide generate physiological effects via selective activation of two closely related membrane receptors with guanylyl cyclase (GC) activity, known as GC-A and GC-B. As yet, however, the discrete roles for ANP/GC-A vs. CNP/GC-B signaling in many mammalian tissues are still poorly understood. We here used receptor affinity labeling and GC assays to char...
