Bioactivity-ELISA
 SN38 ELISA

Immobilized Sacituzumab govitecam at 1 μg/mL (100 μL/well) can bind Monoclonal Anti-SN38 Antibody, Mouse IgG1 (Cat. No. SN8-M685) with a linear range of 0.12-0.98 ng/mL (QC tested).

 SN38 ELISA

Immobilized Monoclonal Anti-SN38 Antibody, Mouse IgG1 (Cat. No. SN8-M685) at 1 μg/mL, add Sacituzumab Govitecam in the 50% Mouse serum and then add Biotinylated Human Her2, His,Avitag, premium grade (Cat. No. HE2-H82E2) at 0.5 μg/mL. Detection was performed using HRP-conjugated Streptavidin (Acro, Cat. No. STN-NH913) (Routinely tested).

Cross Verification
 SN38 CROSS_VERIFICATION

ELISA binding of Monoclonal Anti-SN38 Antibody, Mouse IgG1 (Cat. No. SN8-M685) with Trastuzumab Deruxtecan, Sacituzumab Govitecam, Trastuzumab MMAE and Trastuzumab-DM1 conjugated antibody respectively.

The coating antibody was Monoclonal Anti-SN38 Antibody, Mouse IgG1 (Cat. No. SN8-M685), used at 1 μg/mL concentration. The primary antibody were different payload conjugated antibodies, including Trastuzumab Deruxtecan, Sacituzumab Govitecam, Trastuzumab MMAE and Trastuzumab-DM1 conjugated antibodies used at 0.5 μg/mL concentration. The secondary antibody was Peroxidase AffiniPure Goat Anti-Human IgG, Fcγ fragment specific (min X Bov, Hrs, Ms Sr Prot) (Jackson, Cat. No. 109-035-098) used at 1:12000 concentration.

Monoclonal Anti-SN38 Antibody, Mouse IgG1 (Cat. No. SN8-M685) is specific to Sacituzumab Govitecam and has no cross-reactivity with Trastuzumab Deruxtecan, Trastuzumab MMAE and Trastuzumab-DM1 (Routinely tested).

  • Background
    The 7-ethyl-10-hydroxycamptothecin (SN-38) is a topoisomerase I inhibitor (chemotherapeutic agent) used in cancer therapy. In a comparative study of SN-38 with a potent chemotherapeutic prodrug, irinotecan (CPT-11), SN-38 was found to be 1000-fold more cytotoxic against colorectal cancer cells as compared to irinotecan.
