| Biochemical and Physiological Mechanisms | Fluorescence marker. Selectively targets malignant glioma tissue in vivo when covalently linked to human serum albumin at a molar ratio of 1:1without bleaching nor penetrating into surrounding brain edema or necrotic tissue. Blood-brain barrier permeable. |
| Storage Temp | Argon charged |
| Shipped In | Normal |
| Note | Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour. Toxic, refer to SDS for further information. Need more advice on solubility, usage and handling? Please visit our frequently asked questions (FAQ) page for more details. |
