MultiXtal HT-96 MD1-66 A great addition to any crystallization lab - a 48 condition sparse matrix Hi-PEG crystallization screen offering multiple uses for crystallization. For soluble and membrane proteins. MD1-66 is presented as 2 x (48 x 1 ml conditions). Features of MultiXtal: High PEG concentration screen. Suitable for soluble and membrane proteins. Ideal for counter-diffusion experimentscompatible with CrystalHarp TM. Use in seeding experiments. Available as 10 ml, HT or prefilled microplate (FX) format. Introduction MultiXtal is designed as a high PEG concentration screen for vapour diffusion as well as for use in counter-diffusion experiments and seeding experiments. Contains higher PEG concentrations than found in traditional standard screens; offering greater flexibility in its usage. A buffering range from ph 5.5 to 8.5 ensures appropriate buffering when setting-up crystallizations from 4 C to 37 C. MultiXtal Formulation MultiXtal reagents are formulated using ultrapure water (>18.0 M ) and are sterile-filtered using 0.22 m filters. No preservatives are added. Sodium phosphate used in this screen is Sodium Phosphate dibasic dihydrate, titrated with HCl. 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 MultiXtal formulation, interpretation of results or optimization strategies are welcome. Please e-mail, fax or phone your query to Molecular Dimensions. Contact and product details can be found at www.moleculardimensions.com Crystals growing inside a capillary. 1

User guide for CrystalHarp users only: Recommended use of MultiXtal HT if dispensing with an 8-channel pipette CrystalHarp has 48 individual wells divided into sets of 3 x 16 wells. Due to the spacing of the wells on a CrystalHarp it is not possible to multiple-dispense directly into the first 8 wells with the first 8 conditions (i.e. dispense conditions A1- H1 of a deep-well block into wells 1-8 of the CrystalHarp). So we suggest that the first row of the MultiXtal HT- 96 deep-well block is dispensed into the odd-numbered wells in the CrystalHarp, followed by the second row into the even numbered wells. Repeat for the remaining wells. 1 2 3 4 5 6 7* 8* 9* 10* 11* 12* Dispense column-bycolumn A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 B11 B12 C1 C2 C3 C4 C5 C6 C7 C8 C9 C10 C11 C12 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 E1 E2 E3 E4 E5 E6 E7 E8 E9 E10 E11 E12 HT-96 block layout of MultiXtal.
