Manual & Automated Patch Clamp Service
InquiryMetabolic regulation depends heavily on precise bioelectrical signaling across ion channels in peripheral tissues and central neural networks. In obesity research, ion channels within hypothalamic neurons, pancreatic beta-cells, adipose tissue, and cardiovascular targets dictate energy intake, nutrient sensing, lipid accumulation, and metabolic homeostasis. Characterizing these ion channels requires rigorous electrophysiological platforms capable of evaluating complex ion flux and cellular excitability during lead optimization.
Manual & Automated Patch Clamp Services for Preclinical Obesity Research
Protheragen provides specialized manual and automated patch clamp services specifically designed for preclinical obesity drug discovery. Our platforms support early-stage screening, target validation, lead optimization, and comprehensive cardiac safety profiling. By combining high-throughput automated patch clamp platforms with high-precision manual recordings, Protheragen delivers reproducible ionic current measurements across primary cells, induced pluripotent stem cell-derived models, and recombinant cell lines.
Core Technologies
Our electrophysiology suite leverages complementary manual and automated patch clamp platforms to address the specific functional demands of obesity research:
High-throughput glass chips and multi-channel planar arrays enable rapid functional screening of ion channel targets across thousands of compound interactions daily. APC systems deliver standardized voltage-clamp protocols, automated solution exchanges, and parallel data capture to assess ion channel modulators, pore blockers, and allosteric regulators.
Dual-microelectrode and single-cell manual patch clamp systems offer microsecond temporal resolution and high seal resistance (Giga-ohm seals). Manual patch clamp configurations excel at recording complex endogenously expressed ionic currents, action potential firing dynamics in brain slice preparations, and primary adipocyte or cardiocyte ion conductance.
Microfluidic and rapid solution exchange systems allow sub-second drug application, facilitating precise characterization of fast activation, deactivation, and desensitization kinetics. Precise thermal control units replicate physiological conditions (37°C) to accurately assess metabolic channel kinetics.
Service Scope
Protheragen delivers tailored electrophysiological assays designed around key ion channels implicated in metabolic disease, energy expenditure, and obesity-related comorbidities:
- Central Nervous System (CNS) Appetite & Energy Balance Pathways
Hypothalamic neural circuits, particularly Pro-opiomelanocortin (POMC) and Agouti-related peptide (AgRP) neurons in the arcuate nucleus, control satiety and hunger signaling. We measure ATP-sensitive potassium (KATP) channels, voltage-gated sodium (NaV) channels, hyperpolarization-activated cyclic nucleotide-gated (HCN) pacemaker channels, and transient receptor potential (TRP) channels that govern neuronal membrane potential and firing frequency.
- Peripheral Metabolic Targets & Pancreatic Incretin Axis
Ion channels in pancreatic islet beta-cells and peripheral visceral tissues coordinate insulin secretion, lipid storage, and thermogenesis. Our services measure voltage-gated calcium (CaV) channels (CaV1.2, CaV1.3, voltage-gated potassium (KV) channels, and store-operated calcium entry (SOCE) mechanisms in primary pancreatic islets and adipocyte models.
- Brown & Beige Adipocyte Thermogenesis Profiling
Non-shivering thermogenesis in brown adipose tissue (BAT) and beige adipocytes involves distinct uncoupling mechanisms and membrane ion fluxes. We quantify non-selective cation currents, TRP channel activity (such as TRPV1 and TRPM8), and anion currents that modulate adipocyte mitochondrial potential and cellular differentiation.
- Safety Electrophysiology & hERG Off-Target Profiling
Preclinical drug development for chronic conditions like obesity demands robust early cardiac safety evaluation. We offer comprehensive hERG (KV11.1), NaV1.5, and CaV1.2 cardiac channel panel screens to detect potential QT prolongation risks, cardiac arrhythmia tendencies, and off-target ion channel interactions before advancing compounds into expensive Animal Models.

Frequently Asked Questions
-
Why should we use patch clamp electrophysiology instead of fluorescence-based ion flux assays for our obesity targets?
Fluorescence assays provide useful bulk kinetic data, but they lack real-time voltage control and often fail to detect fast kinetic alterations, voltage-dependent blockages, or subtle gating shifts. Patch-clamp recording remains the gold standard, yielding accurate, direct current recordings and voltage-clamp precision.
-
Can Protheragen record directly from brain slices containing hypothalamic feeding centers?
Yes. Our electrophysiologists perform manual patch clamp recordings on acutely prepared hypothalamic brain slices, allowing direct evaluation of compound effects on POMC, AgRP, or paraventricular nucleus (PVN) neuronal firing rates.
