MemGold2 HT-96 Green Screen MD1-64-GREEN MemGold2 - The latest innovation for crystallization of membrane proteins. This screen targets all alpha helical types of Prokaryotic and Eukaryotic membrane proteins and with our non-covalent fluorescent dye added for superb UV performance. MD1-64-GREEN is a targeted sparse matrix presented as a 96 x 1 ml deep-well block. Features of MemGold2 Green Screen: Contains a non-covalent fluorescent dye (1,8- ANS) for enhanced UV performance. A brand new set of 96 of the most recent alphahelical membrane protein crystallization conditions. Particularly suited for Prokaryotic and Eukaryotic alpha-helical membrane proteins. Increased crystal contrast- observe protein crystals <30µM and also those lacking intrinsic fluorescence. A great addition to any membrane protein lab. Works with MemGold, MemStart, MemSys & MemPlus. Screening over a wider range of ph s (4-10). Addition of small MW PEGs. Can be used in conjunction with Lipidic Sponge Phase and/or Lipidic Cubic Phases. Introduction: In 2008 Molecular Dimensions released MemGold (1) - a rationalized sparse matrix type membrane protein crystallization screen. MemGold was based on the crystallization conditions for 121 alpha helical Membrane Proteins deposited in the PDB. Since MemGold, the number of structures has more than doubled. In response to this, MemGold2 (2) has been developed. MemGold2 includes a further 96 crystallization conditions from unique alpha helical Membrane Protein structures including channel and transporter structures, GPCRs and ATPases. It is suitable for both Prokaryotic and Eukaryotic alpha helical membrane proteins. Formulation Notes: MemGold2 reagents are formulated using ultrapure water (>18.0 MΩ) and are sterile-filtered using 0.22 µm filters. No preservatives are added. Final ph may vary from that specified on the datasheet. Molecular Dimensions will be happy to discuss the precise formulation of individual reagents. Individual reagents and stock solutions for optimization are available from Molecular Dimensions. Enquiries regarding MemGold2 formulation, interpretation of results or optimization strategies are welcome. Please e-mail, fax or phone your query to Molecular Dimensions.

Why use UV fluorescence? In recent years, UV fluorescence imaging has become an established method for protein/salt crystal discrimination. Whilst the majority of proteins contain at least one tryptophan residue there remain a number that fluoresce weakly or not at all, yielding a false negative Green Screens contain a non-covalent fluorescent dye (3), (1,8-ANS, emission at 490 nm) conveys fluorescence on most proteins when illuminated with UV light. This not only increases the signal-to-noise ratio (important for very small crystals), but also allows the identification of protein crystals lacking intrinsic fluorescence that would otherwise remain ambiguous. Use these screens together with UV transparent plates (MD11-00U-100) and ClearVue2 sheets (MD6-19) for optimum UV performance. Features of the Green Screens: Non-covalent binds in channels and not observed to affect crystallization or diffraction quality in any of the proteins tested*. Increased crystal contrast observe protein crystals <30 μm and also those lacking significan intrinsic fluorescence. Improved signal-to-noise on average quantum yield ratio of fluorescence is increased from 0.2 to 0.7. Standard format for all automated systems. a c d b Images of a crystallization drop showing (a) crystals under skin with white light and (b) the same drop under UV- with 1,8-ANS dye and (c) A clear drop under white light?
