As technology evolves, aut<strong>omation</strong> equipment becomes more <strong>and</strong> more capable <strong>and</strong> flexible. With this growing<br />
wealth of capability the dem<strong>and</strong> by the scientist to conduct experiments faster, easier, <strong>and</strong> with higher reliability<br />
is also growing. This duality is creating a new paradigm in laboratory aut<strong>omation</strong>, “Solution Based Systems”.<br />
The traditional laboratory piece wise robotics with a non-coupled LIMS environment is rapidly being replaced<br />
with systems designed to incorporate various pieces of equipment to solve specific problems such as High<br />
Throughput Screen Systems or Automated Protein Crystallization Systems, but this merely marks the beginning<br />
of a broader shift in laboratory aut<strong>omation</strong> trends. Innovations in lab aut<strong>omation</strong> systems continue at a rapid<br />
rate thus today’s state of art is tomorrow’s closet junk. In order to break this cycle <strong>and</strong> provide workable cost<br />
effective solutions <strong>for</strong> the drug discovery arena a radical approach is emerging, Highly Adaptive Integrated Solution<br />
Environments which strongly couple the ease of experiment modification with comprehensive data collection <strong>and</strong><br />
analysis methods to integrated lab aut<strong>omation</strong> solution based systems. This talk will focus on this emerging trend,<br />
discuss the advantages of this new environment <strong>for</strong> both scientist <strong>and</strong> engineer, <strong>and</strong> describe how to get your lab<br />
ready to push the envelope without large upfront costs or long-term paralysis in selecting new <strong>and</strong> replacement<br />
equipment. This talk will conclude with a discussion on how this new trend will benefit the scientist through<br />
automated optimization algorithms which are described in an actual implementation of a hybrid Automated Protein<br />
Crystallization System.<br />

Automated Aptamer Selection: Applications in RNA: Protein Sequence Specificity, <strong>and</strong><br />
Aptamer-chip Microarrays<br />
In vitro selection <strong>and</strong> evolution is incredibly adept at producing nucleic acid binding species (aptamers). Like<br />
antibodies, these nucleic acid aptamers typically interact with their lig<strong>and</strong>s with exceptionally high specificity <strong>and</strong><br />
affinity. Their potential utility become even more evident when one considers the astonishingly large range of target<br />
lig<strong>and</strong>s. Aptamers have been generated to bind lig<strong>and</strong>s ranging from small ions to rat tails. Nucleic acid species<br />
can be manually evolved in significantly less time than required <strong>for</strong> antibody production. Regardless, typical<br />
selections can take upwards of weeks to a few months to finish. Our laboratory has pioneered the process of<br />
automating in vitro selection, facilitating the creation of aptamers in mere days. This ability bodes well <strong>for</strong> the rapid<br />
development of both large-scale aptamer-based evolutionary specificity studies as well as nucleic acid-based<br />
biosensor arrays. Presented herein are examples of these two branches of aptamer employment. Aptamers are<br />
uniquely suited <strong>for</strong> determining sequence recognition motifs of nucleic-acid binding proteins. We have explored the<br />
natural diversity of RNA binding peptides <strong>and</strong> proteins by investigating arginine-rich RNA binding motifs (ARMs)<br />
from eukaryotes, prokaryotes, <strong>and</strong> viruses that infect both. In addition, we have engineered several mutations<br />
of the human spliceosomal U1A protein <strong>and</strong> evolved aptamers to each mutant in order to elucidate nucleic-acid<br />
sequence:protein sequence binding “rules”. Finally, we have created novel aptamer-array chips that function<br />
similarly to traditional DNA-array chips. Aptamers on chips bind lig<strong>and</strong>s as they would in solution, <strong>and</strong> these<br />
biosensing chips allow <strong>for</strong> the parallel measurement of multiple aptamer-lig<strong>and</strong> binding investigations.<br />
