Biological Activity
DBCO-PEG4-VC-PAB-MMAE, an ADC linker comprising DBCO-PEG4-VC-PAB coupled with the tubulin polymerization inhibitor MMAE, serves as a key component in the formulation of antibody-drug conjugates (ADCs). MMAE, a synthetic derivative of dolastatin 10, inhibits tubulin polymerization, acting as a potent mitotic inhibitor.
Target(s): Drug-Linker Conjugates for ADC, Others
Signaling pathway(s): Antibody-drug Conjugate/ADC Related, Others
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
When solubility is listed as < 1 mg/mL, the compound dissolves to less than 1 mg per milliliter in water at 25 °C, pH 7.4. Such compounds require an organic co-solvent such as DMSO to prepare a concentrated stock, which is then diluted into aqueous assay buffer. For cell-based assays, keep the final DMSO concentration below 0.1% (v/v) to avoid solvent-induced cytotoxicity.
Generally, for molecules that require light-protected storage, we will ship them in amber glass bottles.
Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.
- Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
- Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
- Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
- QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
- Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity
To quote quickly, tell us: compound name + CAS/structure (SMILES or mol file), intended assay context, solvent preference, salt/stereochemistry requirements, purity/QC level, and the amount (mg–g).
