Sharpen Up Your Protein Gels
by Bala on September 22, 2008
Last week, Nick talked about about SDS-PAGE. Today I am going to tell you about tweak that will improve your SDS-PAGE protein gels.
It involves using Bis-Tris gel buffers. Although Bis-Tris adds a considerable cost to the (read on...)
Zebrafish: Making Development Transparent
by Dan on February 19, 2008
With the recent development of transparent Zebrafish, allowing scientists to directly view its internal organs, and observe processes like tumor metastasis and blood production after bone-marrow transplant, it seems appropriate (read on...)
Worms: Models of Development
by Dan on January 28, 2008
Continuing with the recent theme on model organisms, there is the nematode (roundworm) Caenorhabditis elegans. This organisms is particularly useful owing to the fact that it has very defined development patterns involving fixed (read on...)
Xenopus as a Model for Early Development
by Dan on January 24, 2008
Another popular model organism is the African Clawed Frog, Xenopus laevis, which is extremely useful for studying development and cellular physiology, owing to its particularly large and easy manipulable oocytes and (read on...)
Dictyostelium as a Model
by Dan on January 23, 2008
As noted in the previous post on Model Organisms, Dictyostelium discoideum is a popular model for studying fundamental aspects of cell-cell communication and chemotaxis. This is a soil-living social amoeba grows as separate, (read on...)
Model Organisms in Biomedical Research
by Dan on January 22, 2008
The term "model organism" is often used in research, to describe species that are extensively studied to understand particular biological phenomena. We say "model," because there is usually the expectation that discoveries made (read on...)
Personal Genomes and Modern Eugenics
by Dan on December 5, 2007
As genetic screening becomes increasingly advanced and personal genomes become more commonplace, the potential for genetic engineering and modern eugenics is becoming a reality. "Designer babies" may not be science fiction (read on...)
