Solvo's core competence: providing tools for Efflux and Uptake Transporter Assays in ADMETox Research

SOLVO offers drug discovery products and services to pharmaceutical companies, relevant to many therapeutic areas. Our in vitro efflux transporter assays and cell lines expressing various uptake transporter proteins answer important questions regarding the interactions between drug compounds and a wide array of transporters.
Moreover, SOLVO Biotechnology offers membrane vesicles prepared from Sf9 (Spodoptera frugiperda ovarian) cells or mammalian cell lines.
The membrane vesicles contain a wide range of different transporters and
can be utilized in various assays. SOLVO Biotechnology provides four
different solutions for ABC (xenobiotic) and uptake transporter assays to
be used in R&D:
Membrane Preparations - for ATPase Assay and Vesicular Transport Assay (direct uptake) measurements
Fee-For-Service Screening
Sublicense for the Calcein Assay
Custom-Made Expression and Screening Systems
Speeding up drug discovery and development
These solutions can significantly speed up the drug discovery and development process. Efflux and uptake transporter assay results - together with physicochemical data and/or monolayer efflux test results - provide an ADME prediction at relatively low cost before the compounds would enter expensive preclinical animal testing. Therefore, application of this technology is a step towards the "fail fast, fail cheap" drug discovery and development philosophy. Another added advantage of our assays over animal testing is that it allows for monitoring interaction of drugs and drug candidates with human proteins.
Applications of transporter assays

The three major applications of ABC Transporter assays are:
Predicting the penetration of test compounds through the
pharmacological barriers (blood-brain barrier, intestinal mucosa,
kidney, liver etc.) = in vitro predictive ADME,
Predicting the penetration of intracellularly active cytostatics into
the cancer cells,
Testing of functional effect of MDR modulators.
How to benefit from our assays?
SOLVO's mainstream products can be used for:
Expression of a wide array of human ABC transporters (MDR1, MDR2/3,
MRP1, MRP2, MRP3, MRP4, MRP5, MRP6, MXR, BSEP and others) and rodent (rat,
mouse) transporters in various expression systems (e.g. baculovirus-based
insect cell)
Functional characterization of proteins (ATPase, transport and binding
data)
Identification of new drug targets on ABC transporters.
Development of various cell lines expressing a range of
pharmacologically relevant uptake transporter proteins
Our unique technology platform is characterized by the following attributes:
Flexible collaboration models for Client focused Services and Reagent sales
Cost-efficiency
Reliability, as only one transporter is expressed in each individual reagent at one time
Easy-to-use methodology with detailed HT protocols available for all reagents (including all insect and mammalian membrane assays)
A wide array of ABC transporter assays and cell lines expressing various
uptake transporter proteins assays are available from SOLVO. SOLVO is
constantly developing new assays, for additional ABC and for other
transporters as well.
The patented Calcein Assay, ATPase Assay and some Vesicular transport
assays are optimized for high-throughput screening on 96 well plates and
widely used by pharmaceutical companies. SOLVO provides full technology
transfer for in-house use as well as fee-for-service screening.
