Protein skimming removes certain organic compounds, including proteins and amino acids found in food particles and fish waste, by using the polarity of the protein itself. . Due to their intrinsic charge, water-borne proteins are either repelled or attracted by the air–water interface and these molecules can be described as hydrophobic (such as fats or oils) or hydrophilic (such as salt ...
Proteins of the erythrocyte membrane separated by SDS-PAGE according to their molecular masses. SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa.
Proteins separated by SDS-PAGE, Coomassie brilliant blue staining. Protein electrophoresis is a method for analysing the proteins in a fluid or an extract. The electrophoresis may be performed with a small volume of sample in a number of alternative ways with or without a supporting medium, namely agarose or polyacrylamide.

The Molecular Operating Environment was developed by the Chemical Computing Group under the supervision of President/CEO Paul Labute. [3] Founded in 1994 [4] and based in Montreal, Quebec, Canada, this private company is dedicated to developing computation software that will challenge, revolutionize, and aid in the scientific methodology.
Krill feeding in a high phytoplankton concentration (slowed by a factor of 12). Filter feeders are aquatic animals that acquire nutrients by feeding on organic matters, food particles or smaller organisms (bacteria, microalgae and zooplanktons) suspended in water, typically by having the water pass over or through a specialized filtering organ that sieves out and/or traps solids.
The Colonial Aircraft of Sanford, Maine developed the C-2 Skimmer in the 1950s as a four-seat variant of the earlier three-seat C-1 Skimmer. The name was changed to Lake in 1959, along with some design improvements. Produced until 1970, this version was designated as the Lake LA-4 Amphibian. [1] [2]
Male flame skimmers are known for their entirely red or dark orange body, this includes eyes, legs, and even wing veins. Females are usually a medium or darker brown with some thin, yellow markings. This particular type of skimmer varies in size but is generally measured somewhere between 2 and 3 inches (5.1 and 7.6 cm) long.
