PEG/Ion 400

Applications

  • Crystallization screen for membrane and soluble biological macromolecules.

Features

  • Reagent formulation developed at Hampton Research
  • Screens a profile of anions, cations, multivalent ions, and neutralized organic acids at varying pH levels in the presence of Polyethylene glycol 400
  • pH range 5 – 9
  • Buffer free formulation
  • Compatible with lipidic cubic phase (LCP), vapor diffusion, microbatch, and free interface diffusion

Description

PEG/Ion 400 is a crystallization reagent kit designed to provide a rapid screening method for the crystallization of membrane and soluble biological macromolecules.

Most G protein-coupled receptors (GPCRs) have been crystallized in Polyethylene glycol (PEG) 400 based reagents1. PEG/Ion 400 is designed as a 96 reagent crystallization screen that is compatible with the Lipidic Cubic Phase (LCP).

PEG/Ion 400 is supplied in a sterile, polypropylene 96 Deep Well block, each reservoir containing 1 ml of sterile filtered reagent. The block is compatible with robotic and multi-channel pipet liquid handling systems and is heat sealed using a special polypropylene backed film. Each PEG/Ion 400 is supplied with an adhesive sealing film which can be used to seal the block after removing the heat seal.

The screen combines a single concentration (30% v/v) of high purity Polyethylene glycol 400 and 48 different high purity salts, comprising both anions (malate, malonate, nitrate, phosphate, succinate, sulfate, tartrate, and thiocyanate) and cations (ammonium, cadmium, calcium, ethylammonium, lithium, magnesium, nickel, potassium, sodium, tetraethylammonium, and zinc) in two concentrations (0.1 and 0.4 M) which due to their unique pH characteristics also affords a reasonable pH screen (approximate pH range of 4 to 9.5). The primary screen variables are PEG, ion type, ionic strength, salt concentration, and pH.
