How to prepare the solution for the laboratory test?

1. Remove the caps from both vials.
2. Apply spirit to a cotton swab and disinfect the rubber bands in both vials.
3. Using an insulin syringe, pour 1 ml of bacteriostatic water into the powder vial (along the wall of the vessel)
4. Roll the vial in your hands or spin the vial making a vortex until the solution dissolves. This activity can be done vigorously, it is important not to foam the solution with strong shaking.
5. The solution prepared in this way gives us a concentration of 2 mg of Tb-500 peptide (43aa) for every 0.2 ml of solution, which should be stored in the refrigerator from now on. You can also prepare the solution in other concentrations as needed.

Storage and transportation

In dry form, the peptide should be stored at room temperature away from direct sunlight. Even longer transportation by courier will not affect the stability and quality of the product.

In wet form (after preparing the solution), the peptide should be in the refrigerator all the time and used up within 30 days.

Research use of the product (TB-500 10 mg + bacteriostatic water)

The product is intended for in vitro research applications only and serves as a reagent used in molecular and cellular analyses targeting cytoskeletal reorganization processes and cell dynamics. In laboratory models it is used for:

• Studies of the interaction of the full sequence of thymosin beta-4 with selected cellular markers and structures involved in cell adhesion and migration,

• To evaluate the effects on the expression of regulatory and structural proteins in cell cultures with different phenotypes,

• analysis of changes in protein levels and activity of potential signaling pathways associated with cellular responses to mechanical and environmental stimuli,

• to support validation, comparison and optimization procedures carried out in molecular biology, cell biology and biochemistry research.
