产品名称：RED Device Insert Removal Tool
货号：Pierce 89812
规格：EACH
The Thermo Scientific Pierce RED Device for Rapid Equilibrium Dialysis was developed in association with the pharmaceutical industry to provide the easiest, fastest and most reliable system for performing plasma protein-binding assays.
The Rapid Equilibrium Dialysis （RED） Device is an apparatus for performing equilibrium dialysis experiments in a high throughput, automation-compatible format. The RED device consists of disposable inserts and a base plate formatted to a standard microplate footprint. The RED Device has been extensively validated for plasma-binding assays and produces results consistent with those reported in the literature. The RED Device offers significant improvements in automation, time requirements, versatility and product reliability compared to other commercially available equilibrium dialysis systems.
Highlights:
Easy and ready to use – disposable tubes require no presoaking, assembly or specialized equipment
Designed for speed – the high surface-to-volume ratio of the insert design enables equilibrium to be reached in as few as 100 minutes with vigorous agitation or in three to four hours with 200rpm agitation
Automation-compatible – designed on a standard 96-well plate template suitable for automated liquid handlers
Flexible and scalable – perform any number of assays （1 to 48 assays per plate） without wasting the entire plate
Robust – compartmentalized design eliminates potential for cross talk or leakage
Reproducible and accurate – validated for plasma binding assays, producing results consistent with those reported in literature
Quality-tested – each lot of inserts is functionally tested in a protein-binding assay for guaranteed performance
Features of the RED Device Inserts:
Each single-use, disposable insert is made of two side-by-side chambers separated by a vertical cylinder of dialysis membrane （in 8K, 12K or 25K MWCO） validated for minimal nonspecific binding. This format requires no extensive assembly steps or specialized equipment, and each chamber or well is easily accessible from the top of the insert after insertion in the base plate. Additionally, the high surface-to-volume ratio of the membrane compartment allows rapid dialysis, where equilibrium can be reached in 4 hours with high levels of reproducibility and accuracy. In many cases, experiments can be completed in less than 100 minutes.
Insert Features:
Disposable: require no presoaking, assembly, or specialized equipment
Short incubation time: large dialysis surface area accelerates equilibrium
8K MWCO membrane: ideal molecular-weight cutoff for protein-drug binding studies
12K or 25K MWCO MWCO membranes are also available for larger drug molecules retained by the standard 8K MWCO
Membrane composition: regenerated cellulose with low glycerol content as a humectant
Features of the RED Device Base Plates:
RED Device Inserts are designed to be used with either the reusable PTFE or disposable high-density polypropylene base plates. Each RED Device Base Plate holds up to 48 RED Device Inserts and has a standard 96-well plate footprint with 9mm x 9mm well spacing to provide compatibility with automated liquid handling systems. In addition, the disposable RED Device Base Plates are available pre-loaded, providing operation convenience for scientists conducting protein-binding applications. No pre-conditioning of the membrane inserts is needed. When using radioactive materials, this single-use plate is easily disposed of to avoid contamination and cleaning. RED Device Inserts and Base Plates are also available separay.
Base Plate Features:
Microplate footprint: compatible with automated systems for 96-well plates
Compartmentalized: eliminates potential for crosstalk or leakage
PTFE construction: eliminates nonspecific binding and risk of contamination
Accepts 1 to 48 inserts: run exactly the number of assays needed without waste
Applications:
Determination of free vs. drug bound to plasma proteins
Pharmacokinetics studies
Formulation of drug dosage for in vivo studies
Drug-drug interaction studies
Selection criteria during drug lead optimization
Drug partition between plasma and whole blood
Solubility study
Dissociation constant determination （Kd）
Tissue-binding study using tissue homogenate
Product Details:
Determining the extent to which a molecule binds to plasma proteins is a critical phase of pharmaceutical development because it influences compound dosing, drug efficacy, clearance rate and potential for drug interactions. This determination is enabled by equilibrium dialysis, an accepted standard method for reliable estimation of the nonbound drug fraction in plasma. Although it is the preferred method, equilibrium dialysis is generally labor-intensive, time-consuming, cost-prohibitive and difficult to automate. The RED Device for rapid equilibrium dialysis was developed in close association with the pharmaceutical industry to specifically address these issues, accelerating lead optimization and reducing the attrition rate. In addition to plasma protein binding, the device is used for determining drug partition between red blood cell and plasma, protein binding of liver microsomes to improve the correlation between in vitro and in vivo intrinsic clearance, the competition between tissue protein binding against plasma proteins and dissociation constant determination （Kd）.
