• A wound dressing that kills bacteria
  

  In order to combat bacterial wound infections, Empa researchers have developed cellulose membranes equipped with antimicrobial peptides. Initial results show: The skin-friendly membranes made of plant-based materials kill bacteria very efficiently. If germs invade a wound, they can trigger a long-l more

• Chemistry-for-Healthcare Start-up secures seed investment
  

  Belyntic, a Berlin-based chemistry-for-healthcare startup and developer of the Peptide Easy Clean (PEC) purification technology, has completed its seed financing round amounting to €1.3 million. The funding is led by the Investitionsbank Berlin (IBB), with the High-Tech Gründerfonds (HTGF) also clim more

• Stem cells moonlight to protect the stomach from bacterial invaders
  

  Our mucosal surfaces are constantly exposed to numerous bacterial species, some of which can induce DNA damage in host cells. Normally this remains inconsequential, as the rapid turnover of the mucosa means damaged cells are shed within days. However, if the long-lived stem cells that continually gi more

• Enzyme Kinetic Measurements for a Combinatorial Library of Inhibitors of Pseudomonas Elastase
  

  Pseudomonas elastase (LasB) is a key drug target in various chronic and intractable infections. A library of 160 potential, in-house synthesised, elastase inhibitors were screened using a fluorescence assay with the internally quenched substra more

• Characterizing Biotherapeutics with HPLC
  

  As demonstrated here, there are a broad range of HPLC applications used in development, production, validation and release of protein therapeutics for human use. Some of the applications mentioned above are mandatory when submitting a new biopharmace more

• Agrisera Western Blot recommendations, troubleshooting and protocol
  

  Each antibody-antigen interaction has unique characteristics. A protocol giving good results for one antibody-antigen pair might found to be unsatisfactory for a second antibody even on the same sample. The interaction of antisera with protein epitop more

A Brief Overview of Classes of Antibiotics

When we’re suffering from a bacterial infection, a trip to the doctors to be prescribed antibiotics is commonplace. However, there are a wide range of antibiotics available, and they vary both in their usage and their mechanism of action. This graphic summarises the major classes, and also gives a b more

The Chemistry of Spider Venom

Spider venoms can be grouped into two broad categories: necrotic, and neurotoxic. Necrotic, or cytotoxic venoms, are those which cause cell and tissue damage after envenomation. This can lead to the appearance of inflammation, lesions, and blisters. Neurotoxic venoms, on the other hand, exert their more

Harnessing evolution to produce new enzymes and antibodies

The last of the 2018 Science Nobel Prizes is awarded, and it was finally the turn of chemistry. The 2018 Nobel Prize in Chemistry was awarded with one half to Frances H Arnold for her work on the directed evolution of enzymes, and with the other half jointly to George P Smith and Sir Gregory P Winte more

• Synergy between conventional antibiotics and anti-biofilm peptides in a murine, sub-cutaneous abscess model caused by recalcitrant ESKAPE pathogens

  by Daniel Pletzer, Sarah C. Mansour, Robert E. W. Hancock With the antibiotic development pipeline running dry, many fear that we might soon run out of treatment options. High-density infections are particularly difficult to treat due to their adaptive multidrug-resistance and currently there are more

• Targeting the potent Beclin 1-UVRAG coiled-coil interaction with designed peptides enhances autophagy and endolysosomal trafficking [Biochemistry]

  Beclin 1 is an essential autophagy protein. Through its coiled-coil domain, Beclin 1 recruits two modulators, Atg14L and UVRAG, to form Atg14L- or UVRAG-containing Beclin 1–Vps34 subcomplexes responsible for Vps34-dependent membrane trafficking processes including autophagy and endosomal trafficking more
