APO-15
Based on 1 Customer Validation
APO-15 is a phosphatidylserine-binding fluorescent probe and apoptosis imaging reagent. APO-15 exhibits high chemical stability under proteolytic and oxidative conditions, enables quantification and imaging of drug-induced apoptosis in preclinical mouse models, and is applicable to fixed tissue samples and multiple in vivo administration routes (Ex = 488 nm; Em = 525 nm). APO-15 can be used in studies related to acute lung injury and breast cancer.

Biological Activity
Apo-15 (50 μM; 24 h) exhibits high chemical stability under proteolytic, oxidative, and physiological buffer conditions, with >95% of the peptide remaining intact after 24 h exposure[1].
Apo-15 (100 nM; 10 min, 10 min at room temperature) competes with AF647-Annexin V for binding sites on apoptotic human neutrophils, confirming PS as its molecular target[1].
Apo-15 (100 nM; 10 min at room temperature) binding to apoptotic human cells is dependent on externalized PS, as it fails to stain apoptotic cells that cannot translocate PS to the outer membrane[1].
Apo-15 (100 nM; 15 min, 1000 s) enables wash-free, real-time imaging of apoptotic progression in live human lymphoid cells, with rapid fluorescence activation upon PS exposure[1].

APO-15 (5 μM; i.v.; single administration) detects cisplatin-induced apoptosis in mouse MMTV-PyMT breast cancer tumors, with signal co-localizing with the apoptotic marker cleaved caspase-3[1].

Animal Model:C57BL/6 (8-12 weeks old; induced by intratracheal instillation of E. coli-derived LPS, S. aureus-derived LTA and PepG)[1]
-
Dosage:5 μM
-
Administration:intratracheal; single administration
-
Result:Showed 29% of CD45+Ly6G+ neutrophils in BALF stained positive, compared to 5% in LPS-only treated mice. Detected 90 APO-15-positive cells per 0.25 μm2 section in lung tissue from LPS + CDKi-treated mice, compared to 32 cells per 0.25 μm2 section in LPS-only treated mice. Demonstrated negligible staining in healthy saline-injected control mice, and bright, stable staining in the lungs of mice with ALI.

Animal Model:MMTV-PyMT (C57BL/6 background; tumors grown to 0.5-1 cm size)[1]
-
Dosage:5 μM
-
Administration:i.v.; single administration
-
Result:Retained signal in tumor tissues after OCT embedding and sectioning. Co-localized with staining for cleaved caspase-3, confirming detection of apoptotic cells.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (1.91 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (1.91 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
