Functional analysis of the proteome is an essential part of genomic research. To facilitate different proteomic approaches, a MORF (moveable ORF) library of 5854 yeast expression plasmids was constructed, each expressing a sequence-verified ORF as a C-terminal ORF fusion protein, under regulated control. Analysis of 5573 MORFs demonstrates that nearly all(More)
Over the past 5 years, protein-chip technology has emerged as a useful tool for the study of many kinds of protein interactions and biochemical activities. The construction of Saccharomyces cerevisiae whole-proteome arrays has enabled further studies of such interactions in a proteome-wide context. Here, we explore some of the recent advances that have been(More)
We synthesized reversible terminators with tethered inhibitors for next-generation sequencing. These were efficiently incorporated with high fidelity while preventing incorporation of additional nucleotides, and we used them to sequence canine bacterial artificial chromosomes in a single-molecule system that provided even coverage for over 99% of the region(More)
We present the application of an activity-based phage display method to identify DNA polymerases tailored for next generation sequencing applications. Using this approach, we identify a mutant of Taq DNA polymerase that incorporates the fluorophore-labeled dA, dT, dC, and dG substrates ~50 to 400-fold more efficiently into scarred primers in solution and(More)
We describe a method for making and erasing barriers to the lateral diffusion of membrane components in fluid lipid bilayers supported on glass substrates. When a bilayer is mechanically partitioned by scratching the membrane-coated surface at basic pH, barriers to lateral diffusion are formed which prevent mixing between the regions separated by the(More)
To further understand the roles of protein glycosylation in eukaryotes, we globally identified glycan-containing proteins in yeast. A fluorescent lectin binding assay was developed and used to screen protein microarrays containing over 5000 proteins purified from yeast. A total of 534 yeast proteins were identified that bound either Concanavalin A (ConA) or(More)
Two methods for patterning surfaces with supported lipid bilayers and immobilized protein are described. First, proteins are used to fabricate corrals for supported lipid bilayers. Poly(dimethylsiloxane) stamps are used to deposit arbitrarily shaped patterns of thin layers of immobilized protein onto glass surfaces. This is followed by vesicle fusion into(More)
We recently introduced a method to tether intact phospholipid vesicles onto a fluid supported lipid bilayer using DNA hybridization (Yoshina-Ishii, C.; Miller, G. P.; Kraft, M. L; Kool, E. T.; Boxer, S. G. J. Am. Chem. Soc. 2005, 127, 1356-1357). Once tethered, the vesicles can diffuse in two dimensions parallel to the supported membrane surface. The(More)
tion in affected monolayer regions, as the enhanced aliquid-likeo character of debonded tails would give rise to an enhanced viscous drag opposing the motion of the tip. [10] Attempts to remove from the surface monolayer molecules (following inscription of patterns in the non-destructive patterning regime) by solvent treatments with sonication and(More)
The fields of antibody engineering, enzyme optimization and pathway construction rely increasingly on screening complex variant DNA libraries. These highly diverse libraries allow researchers to sample a maximized sequence space; and therefore, more rapidly identify proteins with significantly improved activity. The current state of the art in synthetic(More)
