Stain-free gel chemistry uses a unique compound, which, when activated, reacts with tryptophan residues in the protein sample to emit a fluorescence signal. This allows the quick visualization of proteins without any staining steps. In addition, stain-free gel chemistry makes it possible to use total protein levels as a loading control rather than the housekeeping proteins used in traditional western blotting protocols. This negates the need to strip and reprobe blots and prevents any attendant errors that can be introduced at this step.

With the announcement July 2 that BP has settled federal, state and local claims related to the 2010 Deepwater Horizon oil spill for a total of more than $18.7 billion, leaders with Texas’ RESTORE Centers of Excellence are moving forward with plans to use millions in spill-related Clean Water Act funding on research and science activities that will benefit Texas and help to restore the health of the Gulf of Mexico.

A research group at Umeå University has managed to capture and describe a protein structure that, until now, has been impossible to study. The discovery lays the base for developing designed enzymes as catalysts to new chemical reactions for instance in biotechnological applications. The result of the study is published in the journal Nature Communications.

The first comprehensive analysis of the woolly mammoth genome reveals extensive genetic changes that allowed mammoths to adapt to life in the arctic. Mammoth genes that differed from their counterparts in elephants played roles in skin and hair development, fat metabolism, insulin signaling and numerous other traits. Genes linked to physical traits such as skull shape, small ears and short tails were also identified. As a test of function, a mammoth gene involved in temperature sensation was resurrected in the laboratory and its protein product characterized.

Spiny lobsters practice “behavioral immunity” to create safe havens that prevent them from contracting a lethal disease in the wild, an important finding for the $50 million annual spiny lobster fishery in Florida, according to a new study co-authored by a University of Florida scientist.

Weizmann Institute scientists develop an “olfactory fingerprint” test that may do more than just identify individuals.

In a new Research Frontiers video, University of Arkansas biologist J.D. Willson and his graduate students search for reptiles and amphibians at Woolsey Wet Prairie Sanctuary on the outskirts of Fayetteville. Willson’s research group has found rare species in the restored prairie wetland, such as the Graham’s crayfish snake and the crawfish frog.
