News Membranes

• Superglue for cells

  Scientists in Canada have developed a super-strong membrane adhesive that can stick red blood cells together. The polymer, which is based on the phospholipid head group phosphatidyl choline, could be used to secure cells in particular positions for tissue engineering and wound closure. Research desc more

• New plant protein discoveries could ease global food and fuel demands

  New discoveries of the way plants transport important substances across their biological membranes to resist toxic metals and pests, increase salt and drought tolerance, control water loss and store sugar can have profound implications for increasing the supply of food and energy for our rapidly gro more

• Skin-deep communication: Messenger substance and signaling molecule influence the development of the skin’s immune cells

  A signalling molecule known as Axl has been discovered on immune cells of the epidermis. This recently published finding provides new insight into the development of important skin immune cells known as Langerhans cells. These cells fight off invading microorganisms and play a crucial role in our he more

• Membrane Fluidity Measurements Using UV Fluorescence Polarization and the POLARstar Omega
  

  The POLARstar Omega microplate reader from BMG LABTECH was used to study membrane fluidity via fluorescence polarization in 96-well format. The method allows for the monitoring of large scale alterations in membrane fluidity (such as phase transitions), as well as more subtle changes in lipid dynamic. The change in polarization caused by dibucaine and propranolol were investigated in both liposomes and mitochondrial membranes more

• Analysis of water soluble polymers using linear size exclusion HPLC columns and a semi-micro SEC system
  

  One of the most widely used water-soluble polymers is Polyvinylpyrrolidone (PVP). For more than 70 years it is applied in a variety of applications in medicine, pharmacy, cosmetics and industrial production. PVP binds to polar molecules exceptionally well. It supports the solubility of tablets in water, makes the glue stick adhesive and plays an essential role in the production of membranes. In ceramic, paper and dye applications, it produces visual effects such as gloss and brilliancy. As a food additive, PVP is a stabilizer (E1201). A characteristic feature of a certain polymer is its molecular weight distribution curve, which is usually obtained by SEC Analysis more

• Functional Analysis of Side Effects of Transfection Reagents in the Context of Bax-induced Apoptosis
  

  FuGENE® HD Transfection Reagent is well-suited for studying the impact of apoptosis-inducing proteins such as bax. Transfection with FuGENE® HD Transfection Reagent produced only minimal cytotoxic side effects while maintaining a high transfection efficiency. In contrast, cytotoxicity, and off-target effects of the other commercially available transfection reagents tested made it impossible to distinguish the impact of the bax protein from the impact of the transfection reagent itself more
