Biological Activity


Targets HIV-1
ln Vitro Exogenous Tat protein can translocate across the plasma membrane and enter the nucleus, where it can activate the viral genome, according to studies. At the normal dosage of 1 mM, the HIV-1 TAT (48-60) peptide, which only comprises the basic domain of the full length peptide, maintains the entire translocation activity and even seems to be more effective in terms of nuclear localization when compared to the other active peptides[1]. Large, hydrophilic molecules can be delivered intracellularly using cell-penetrating peptides, which are thought to be a potential vector. Confocal laser scanning microscopy shows an apparent endocytotic absorption of HIV-1 TAT (48–60)[2]. The production of rod-shaped, possibly inverted micelles in DMPC is induced by HIV-1 TAT (48–60), and these micelles may serve as intermediates while translocating across eukaryotic membranes[3].

Solubility Data


Solubility (In Vitro) DMSO : ≥ 100 mg/mL (58.17 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 2.5 mg/mL (1.45 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.5 mg/mL (1.45 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

Solubility in Formulation 3: ≥ 2.5 mg/mL (1.45 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
