Description

5(6)-TAMRA is a fluorescent dye molecule widely used as a label for peptides and proteins.

In Vitro

1. Peptide Labeling:
The polypeptide R9 was incubated with TAMRA (4-equivalent) in dimethylformamide containing benzotriazole-1-acyloxy-tripyrodiene-phosphohexafluorophosphate (4-equivalent) and diisopropylethylamine (8-equivalent) for 4 hours and labeled on the resin. Wash the resin with dimethylformamide and methylene chloride, and then de-protect as described above.
2. Peptide Internalization:
CHO cells were inoculated with Ham's F-12 medium in a 4-well Lab-Tek-II chamber slide (Nalge Nunc International, Naperville, IL). Labeled peptides were added to each slide and incubated at 37°C. After 60 minutes, cells were washed with PBS containing Ca2+ (0.1 g/L) and Mg2+ (0.1 g/L) (6 times). Fluorescence microscope observation.
3. Heparin-Affinity Chromatography:
The labeled peptide (~ 2mg) was loaded onto the column and eluted in the same buffer with a linear gradient of NaCl (0-2 M). Peptide elution was monitored at 280 nm and 535 nm absorbance.
4. Binding of TAMRA–R9 to Heparin:
When TAMRA-R9 binds to soluble heparin, fluorescence enhancement at 590 nm (excitation:531 nm).

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2.08 mg/mL (4.83 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.
 If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
