| Description | Tetraphenylporphine sulfonate (TPPS) serves as a non-cytotoxic probe suitable for tumor localization detection [1]. |
| In vitro | TPPS（0-20 μg/mL）在体外对Vero和HEp-2细胞无毒性，并且主要位于细胞中的可溶性与蛋白质部分[1]。 |
| In vivo | TPPS4在96小时后注射呈现出最高的肿瘤对组织比例，且这一比例随剂量增加而变化[2]。TPPS4似乎通过肾脏清除，且注射后随时间增长其在肾脏中的绝对浓度有所下降[2]。 |
