PCR Primed To Spur Chain Of Applications
Holly Ahern | Jun 25, 1995 | 10+ min read
What would you do if your research interests revolved around obtaining DNA from a bacterium preserved for millions of years in the gut of a bee stuck in amber, matching up a murderer to crime- scene blood half a century old, or cloning genes from a 1,000- year-old mummy? Most scientists would first consider PCR--the polymerase chain reaction--as a technique for approaching problems such as these. With PCR, minute quantities of nucleic acids can be amplified millions of times into sufficient qua
Surpassing the Law of Averages
Jeffrey M. Perkel | Sep 1, 2009 | 7 min read
By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo
Going Their Separate Ways: A Profile of Products for Cell Separation
Michelle Vettese-dadey | Sep 12, 1999 | 10+ min read
Date: September 13, 1999Cell Separation Products Magnetic Cell Separation Technologies that isolate rare cell types to high purity are essential to the cell biology researcher. Understanding cell developmental pathways becomes increasingly significant as diagnosis and treatment of disease turns more to the molecular level.1 This diagnosis of cell-related diseases requires methods for detection, isolation, and analysis of individual cells regardless of their frequency.2 The hematopoietic system

According to Protocol
Barbara Cunningham | Apr 15, 2001 | 8 min read
Nearly all scientists involved in basic biomedical research are familiar with the "Red Book" (Current Protocols in Molecular Biology)1 and Molecular Cloning: A Laboratory Manual.2 These well-known, time-tested books are still considered "bibles" in research laboratories, containing a wide range of basic techniques used by most life scientists. However, as scientific studies and experimental designs become more intricate and specialized, so do the techniques involved. As a result, detailed, "spec

PP.22 Date:October 3, 1994 Molecular Bio-Products' Turbo Assay System is a membrane and manifold system for a wide variety of qualitative and quantitative assays. The system provides a format for colorimetric and radiometric assays and is said to reduce total assay time to as little as 15 minutes. The disposable 8-well assay strips ensure no cross-talk between samples. The incorporated membrane has a high protein binding capacity a
