What Do You Know About Your Target? The sensitivity needs of your system are primarily determined by the abundance of your target, which can be approximated according to its origin. Plasmids, cosmids, phagemids as colony lifts or dot blots, and PCR products are usually intermediate to high-abundance targets. Genomic DNA is considered an intermediate to low-abundance target. Most prokaryotic genes are present as single copies, while genes from higher eukaryotes

Air Buoyancy Akin to water keeping something afloat, samples can be “lifted” by air, artificially decreasing their apparent weight. This air buoy￾ancy can have a significant effect on smaller samples. Electrostatic Forces Electrostatic charges are almost always present in any environ￾ment, particularly in areas with very low humidity. If there are

This book celebrates the importance of the question; it is not meant to be a collection of facts or procedures. The writing of this book was inspired by 16 years of queries from the research community.The con￾tributors and I have tried to meet two primary objectives:

Over the past decade the variety of hosts and vector systems for recombinant protein expression has increased dramatically. Researchers now select from among mammalian, insect, yeast, and prokaryotic hosts, and the number of vectors available for use in these organisms continues to grow

What Are the Symptoms of Acrylamide Poisoning? The initial symptoms of acrylamide poisoning on the skin are peeling of the skin at the point of contact, followed by tingling and numbness in the exposed area. If exposure by any means (touch, ingestion, inhalation) continues, muscular weakness, difficulty maintaining balance
