With individual membranes and fluid directors within each cavity, the cross contamination between wells is eliminated. Filter plates are specifically designed for a clog-free liquid flow completed at a fast and uniform rate for higher yields. Common well formats are compatible for use with standard processing equipment.
removed prior to use by filtering a small amount of warm purified water through the membrane or filter unit. Surfactant-free cellulose acetate membranes with very low levels of extractables are available on some Corning® syringe filters. Cellulose nitrate (CN) membranes are recommended for filtering solutions where protein binding is not a
Low-protein-binding membranes with a pore size of 0.22 microm are used to filter aqueous solutions containing viruses. Virus adsorption to the membranes is avoided if they are made of polyvinylidene fluoride (PVDF) or if they are made of cellulose esters saturated with beef extract.
Nov 12, 2020 · To measure protein binding (PB) % of test compounds in human and rat (if needed) serum. Approximately 10 µL of 10 mM test compound in DMSO will be used to determine the % value at single concentration, 10 µM. Pros: Cons: • Simple procedure • High non-specific binding to filter membrane • 4 compounds/ day Pros: Cons: • Accuracy • Low
GH Polypro (GHP) Membrane Disc Filters Hydrophilic polypropylene membrane with maximum chemical compatibility when filtering both aqueous solutions and aggressive solvents. High recovery of critical proteinaceous samples due to low protein binding. HPLC certified. 47mm diameter. Pore size: 0.2um.

Product description. "These syringe filters offer a choice of filter media: hydrophobic PTFE membrane for exceptional chemical and temperature compatibility -hydrophilic nylon membrane for excellent chemical compatibility with esters, bases, and alcohols, without prewetting -GHP (hydrophilic polypropylene) membrane for low protein binding -and hydrophilic PVDF (polyvinylidine fluoride) membrane for use in aqueous and nonaggressive, solvent-based mobile phases.
Hawach PES Membrane Filters, with low extractability, high flow rate, and good strength. PES membrane provides excellent downstream cleanliness, and low protein binding for cell culture applications, such as media, sera, and growth. PES membrane filter does not adsorb proteins and extracts and does not pollute the sample.
Pall GHP Polypropylene membrane will be discontinued effective October 31st, 2019. This discontinuation affects devices including syringe filters, filter plates, centrifugal devices and membrane filter discs. Syringe filters are attached to the end of a syringe to remove particles from a sample prior to analysis. Filtering liquids, the single-use devices force liquids through the filter either
GHP (hydrophilic polypropylene) membrane is low protein binding. Both nylon and GHP membrane filters include a glass fiber prefilter layer, as well as being HPLC certified for low UV-absorbing extractables. The regular glass fiber membrane has very low extractables. Polypropylene housing. Female luer lock inlet and male slip luer outlet.
A selection of different membranes commonly used to bind proteins in blotting and dot binding assays were investigated for a range of properties which would influence their performance. Large differences were observed in the membranes' ability to bind increasing amounts of protein, the effect of inc
