Irinotecan is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. SN38 is 1000-times more active than irinotecan, but is not generally used as a drug due to its poor water solubility. If it is conjugated to a protein or antibody, the protein/antibody can transport SN38 to the active site. 

This product is a control ADC for any IgG antibody labeled with SN38, in particularly ADC made using CellMosaic's ADC Kits (Cat#: CM11408). The product uses a human IgG1 subtype antibody that does not bind to the target. It has an average 4 SN38 loaded on each antibody and can be used for accessing the effect of SN38 alone (non-specific toxicity). The product uses a very low endotoxin level antibody as a starting material (≤0.5 EU/mg by the LAL method). The preparation and purification are conducted under pyrogen free environment. The final product is assayed for endotoxin to make sure it is suitable for cell culture and animal studies. The loading is confirmed by various methods including UV and difference MALDI-TOF MS.

The final conjugate is lyophilized from phosphate buffered saline containing sugar-based stabilizer for easy shipping and storage. 

The product is sold as 1 vial of 100 microgram (Cat# CM51102-100UG), 1 vial of 500 microgram (Cat# CM51102-500UG), or 2 vials of 500 microgram (Cat# CM51102-1MG). For bulk orders, please contact us for a quote.
