polystyrene vs polypropylene cell culture

 It was a stupid mistake that I thought only I was capable of making, until a month later when a tech from a brand new lab stopped by to ask what kind of conical bottom tubes we used, and asked very specifically about maxipreps. Monomers bind with each other via covalent bonds to form a polymer. Polypropylene tubes can be centrifuged at 3000 × g and sterilized at 120°C. Like all polyolefins, polypropylene is non-toxic, non-contaminating and lighter than water. Its monomer is propylene, which has three carbons and one double bond between two of those carbon atoms. My samples are in formamide so I'm getting polypropylene. Today, polyethylene is commonly manufactured in several different forms with vastly different properties: 1. What is Polypropylene What is Polystyrene  Polystyrene is useful in making toys, kitchen appliances, disposable drinking cups, packaging material, computer housing parts, etc. Polypropylene is also a plastic polymer. Summary. Polyethylene Terephthalate (PET) – PET is known for its ability to be easily ther… Krzysztof Matyjaszewski, in Comprehensive Polymer Science and Supplements, 1989. Selecting and coating ELISA plates When developing a new ELISA for a specific antigen, the first step is to optimize the plate-coating conditions for the antigen or capture antibody. The key difference between polystyrene and polypropylene is that the monomer for polystyrene is styrene, while the monomer for polypropylene is propylene. Moreover, we can recycle polystyrene. Furthermore, according to the pattern in which the phenyl groups (pendant groups) attach to the carbon chain, there are three types of the polymer: isotactic (all phenyl groups are on the same side of the chain), syndiotactic (the phenyl groups are in two sides in an alternating pattern) and atactic (the phenyl groups attach in a random pattern). Polypropylene vs Polystyrene. Shop a large selection of products and learn more about Fisherbrand™ 96-Well DeepWell™ Polypropylene Microplates: Microplates Dishes, Plates and Flasks . Furthermore, the pendant group of polystyrene is a phenyl group while the pendant group of polypropylene is a methyl group. Both polystyrene and polypropylene are useful polymer materials we use in our daily life. These repeating units are …  Losing someone else’s day and a half is, well, infinitely worse. These tubes are molded from either premium-grade polystyrene for clarity, or polypropylene for impact strength and stability to common acids, alkalis, and solvents.High-quality glass test tubes, and plastic test tubes are designed and constructed for optimal performance and excellent resistance to industrial scientific chemicals. by Rachel Schecter. Polymers are large molecules, which have the same structural unit repeating over and over.  These repeating units are “monomers”. Falcon® Round-Bottom Polypropylene Tubes, 5 mL are sterile, high-quality tubes ideal for a wide variety of sample preparation, sample storage, and sample centrifugation tasks. Adherence of certain cell types to poly-lysine-coated surfaces is based on the electrostatic interaction of the poly-D-lysine polycation with the negative charges of the cell membrane. We can manufacture polystyrene via free radical vinyl polymerization and polypropylene via chain-growth polymerization. Can you grow your cells in normal polystyrene plates, then lift and transfer them to polypropylene plates and do the extractions in those?  That’s when a hammer and the desire to destroy things comes in handy. Thus, polystyrene and polypropylene are two such polymers. “Polypropylene Wipe Detail” By BlueThunderTechnologies – Own work (CC BY-SA 4.0) via Commons Wikimedia. polypropylene tubes can withstand 3000 RPM and are autoclavable and freezable. The Evolution of Polystyrene as a Cell Culture Material Max J. Lerman, MS,1–3 Josephine Lembong, PhD,3,4 Shin Muramoto, PhD,2 Greg Gillen, PhD,2 and John P. Fisher, PhD3,4 Polystyrene (PS) has broughtinvitrocell culture from its humble beginningsto themodernera, propelling dozens of research fields along the way. Both Polypropylene and polyethylene are a form of plastic- a plastic material known as a polymer. General purpose polystyrene is clear, hard, and brittle and as a thermoplastic polymer it is in a solid glassy state. … 1. 1. “Polypropylene.” Wikipedia, Wikimedia Foundation, 10 Mar. A quick Google search shows that there's plenty of polypropylene microplates, but tissue culture treatment of these seems rare. Moreover, they have a high molecular weight and consist of over 10,000 atoms.  In the synthesis process, or “polymerization”, we can obtain longer polymer chains. Below infographic summarizes the difference between polystyrene and polypropylene. Polypropylene has the following important properties: Due to the above properties, this material is useful for the production of pipes, containers, houseware, and packaging and automotive parts. Imaging … The resulting polymer could be formed into sheets and rods, or drawn into fibers and films. A lot of little details in lab go unmentioned, yet can make or break an experiment, and you won’t know it until things either don’t work, or go horribly awry. Structure looks similar with carbons and hydrogen molecules- but then the differences arise useful.
