  • Removing supernatant after centrifugation Nanotrap Particle technology provides a simple solution to complex problems by offering the capability to enrich, preserve, and screen low-level biomarkers directly from complex biological samples. This video shows how supernatant is removed from Nanotrap particles after centrifugation. Remove your biofluid or wash media after centrifugation by carefully pipetting the supernatant away from the Nanotrap particle pellet containing your harvested biomarkers.

  • Flexifuge Centrifuge Rotor Installation Instructions Argos Technologies versatile, personal micro-centrifuge for quick, low speed centrifugation. Whisper quiet motor offers two speeds (2000g / 6000 or 9200 RPM ) depending on application. Flexifuge can be operated in continuous mode, pulsed for a short burst of rapid centrifugation, or timed to spin from 1-20 minutes. Regardless of setting, rotors stop once the lid release button is pushed. A ring of LED lights illuminate when the unit is active and can be viewed through the transparent lid. Color can be changed (red, green, blue) or turned off by a switch under the unit. Flexifuge is supplied with an 8-Place fixed angle rotor for 1.5mL tubes, a rotor for (4), 8 x.2mL PCR tube strips and 8 adapters for .5mL tubes. It can also accommodate a 4-place rotor (purchased separately) to spin 5mL micro-centrifuge tubes.

  • Protein Characterization I This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. Folding of proteins is dictated by the sequence of amino acids. Folding does not occur randomly. If it did, proteins would take longer than the age of the universe to fold and instead they fold in seconds. This is known as Levinthal's paradox. 2. The tendency of each amino acid to participate in alpha helices, beta strands/sheets, and turns are known and this information can be used to predict secondary structure of a protein from the amino acid sequence. 3. Misfolding of proteins can have disastrous consequences (but not necessarily always). One disastrous consequence is that of prions, which are "infectious" proteins implicated in diseases, such as mad cow disease and Creutzfeld-Jacob disease in humans. Each of these is a brain-wasting disease the results from misfolding of a brain protein known as PrP. The misfolded protein apparently helps convert properly folded proteins to the misfolded state and cause the disease. 4. Cells use chaperonin complexes to help insure proteins fold properly. Chaperonins are induced by heat shock of cells. Protein Purification 1. Purification of proteins exploits differences in charge, size, shape, and affinity for specific compounds. Centrifugation (artificial gravity) provides a means of precipitating cellular components. The faster one spins the rotor of the ...
