Frequently Asked Questions
What is a small molecule inhibitor?▼
A small molecule inhibitor is an organic compound (typically with molecular weight <500 Da) that binds to a specific protein target and reduces its activity. These compounds are essential for research into signal transduction, drug discovery, and understanding biological pathways. They form the foundation of modern drug development and are invaluable tools in molecular and cell biology.
How do I choose the right inhibitor for my target?▼
Consider your target protein, desired selectivity, potency (IC50 values), cell permeability, and whether you need in vitro research applications. We provide extensive data including IC50 values, selectivity panels, and pharmacokinetic information for each compound. Our PhD-level team can help recommend the ideal compound for your specific research goals.
What purity levels are available?▼
All Immunomart compounds are research-grade with >95% purity verified by HPLC/MS. Each compound includes a detailed certificate of analysis (CoA) that specifies purity percentage, molecular identity confirmation, NMR data, and solubility specifications. Higher purity grades (>98%) are available upon request.
How should I store and handle these compounds?▼
Storage requirements vary by compound and are specified in each CoA. Most powder compounds are stable for 2+ years at -20°C in a desiccated environment. DMSO solutions are typically stored at -20°C, protected from light. Always use fresh aliquots to minimize freeze-thaw cycles, which can compromise compound stability. For long-term storage, we recommend -80°C.
Do you offer DMSO solutions?▼
Yes. Most compounds are available in powder form. Many are also offered as pre-made 10mM DMSO solutions, which are convenient for high-throughput screening and assay setup. Custom concentrations and other solvents are available upon request. DMSO solutions are particularly useful for large screening campaigns.
What is the difference between an inhibitor, agonist, and modulator?▼
An inhibitor reduces or blocks protein activity or receptor signaling. An agonist activates a receptor or increases protein activity. A modulator can either increase or decrease activity depending on context and cellular environment. Our catalog includes all three types across diverse targets, enabling comprehensive research approaches.
Can I get bulk or custom quantities?▼
Absolutely. Most compounds are available in multiple quantities (1mg, 5mg, 10mg, 25mg, 50mg, 100mg and larger). Custom syntheses and bulk orders are available through our team. For your specific needs, including non-standard quantities or modifications, please contact our team to request a quote.
How quickly do you ship to the US, Canada, and Europe?▼
Typical delivery times: US 2-3 business days, Canada 3-5 business days, Europe 5-7 business days (customs dependent). Expedited and overnight shipping are available for urgent orders. All shipments include tracking information and insured packaging to protect your compounds in transit.
What formats and formulations are available for these compounds?▼
Our compounds are available in multiple formats including DMSO solutions and powder forms. We provide IC50 data, selectivity panels, and characterization information to guide your selection. All products are for research use only. Consult our team for specific research applications.
Do you provide certificates of analysis (CoA)?▼
Yes. Every compound includes a comprehensive CoA with HPLC/MS purity analysis, molecular weight confirmation, NMR data, and solubility specifications. CoAs are available for immediate download after purchase and can also be requested via email. These documents are suitable for publication and regulatory compliance.
