Order Crystallization Screens: JBScreen Nuc-Pro
JBScreen Nuc-Pro is designed to screen for preliminary crystallization conditions of nucleic acids and protein-nucleic acid complexes.
The highly effective sparse matrix screen is based upon extensive screening of the PDB [1], with focus on entries by structural genomic initiatives, the BMCD [2] and other protocols [3-5]. Reported crystallization conditions for various RNAs, DNAs as well as protein-nucleic acid complexes were compiled and analyzed for rate of recurrence.
The 96 conditions selected cover a variety of polymers, mono- and divalent metal ions, organics, alcohols and buffers of a pH range from 4.0 to 8.5. The organization of the reagents into individual kits is based upon the main precipitant, i.e. various molecular weight PEGs, Salts, alcohols (MPD and 2-Propanol).
JBScreen Nuc-Pro is available as 4 individual kits containing 24 reagents each in 10 ml bulk format or in a pre-filled 96 deep well block.
The ready-to-use reagents are tested for DNase contamination using JBS DNase Detection Kit.
