Figure 1. Optimization of double-antigen sandwich ELISA. (a) Capture (0.5 to 5.0 µg/mL) and detection antigen (0.2 (green), 0.4 (light blue), 0.8 (yellow), and 1.6 (purple)) were used to optimize capture and detection antigen (N protein). Capture antigen was diluted with Antigen Coating Buffer. From Figure 1a of Cordero-Ortiz, M, et al. (2023) Animals (Basel) 13, 3487 doi: 10.3390/ani13223487.

Assay Protocol
1. Dissolve camptothecin powder in tissue culture grade DMSO to obtain a 2 mg/mL comptothecin stock concentration., 2. Prepare 50 – 100 µL aliquots of the DMSO solubilized camptothecin and store them frozen at < -20°C. A frozen vial of camptothecin may be re-thawed 2X before discarding. Vials which have been thawed 1X should be marked to indicate this so that they only go through one more freeze thaw before being discarded. 3. Spike cell cultures at a camptothecin concentration range of 2 – 4 µg/mL which yields a cell culture camptothecin concentration of 6 – 12 µM. This camptothecin concentration range works Well for inducing Jurkat or HL 60 cell suspensions which usually run in the 1 x 105 – 1 x 106 cell/mL concentration range. At this concentration range successful apoptosis induction has been achieved after a 4 hour (37°C) incubation period. 4. Perform time course studies on your particular cell line to ascertain the optimal camptothecin concentration and exposure time required to achieve good apoptosis induction levels for your experiments. 5. Proceed with your experimental apoptosis induction model system.

Target Description
Cathepsin D is a ubiquitous lysosomal aspartyl protease that functions in protein degradation and apoptosis. It can also be secreted from the cell and is implicated in disease states such as tumor growth and metastasis. Purified from human liver tissue and tested to be negative for HbsAg, anti-HBc, anti-HCV, and anti-HIV-1 and -2. This product is best used to study enzyme kinetics, cleave target substrates, and screen for inhibitors.
