| Purity | Greater than 90.0% as determined by SDS-PAGE. | Source | Escherichia Coli. |
| Phycical Appearance | Sterile Filtered and lyophilized, though might appear as a solution as a result of the glycerol content. | Shipping Condition | Shipped at Room temp. |
| Amino Acid Sequence | MEPVDPRLEP WKHPGSQPKT ACTNCYCKKC CFHCQVCFIT KALGISYGRK KRRQRRRPPQ GSQTHQVSLS KQPTSQSRGD PTGPKE. | ||
| Solubility | It is recommended to reconstitute the lyophilized HIV-1 TAT in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
| Stability | Lyophilized HIV-1 TAT although stable at room temperature for 1 week, should be stored desiccated below -18°C . Upon reconstitution HIV-1 TAT should be stored at 4°C between 2-7 days and for future use below -18°C .For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. | ||
| Formulation | Lyophilized with 0.1% glycerol. | ||
Human immunodeficiency virus type-1 (HIV-1) regulatory Tat protein plays an essential role in viral replication (Jones KA, 1994) and infectivity (Arya SK, 1985; Fisher AG, 1986). In addition, during acute infection, Tat is released extracellularly by infected cells (Chang HC, 1997; Ensoli B, 1990) and is taken up by neighboring cells where it transactivates viral replication (Ensoli B, 1993) and increases virus infectivity. HIV-1 Tat activates transcription of HIV-1 viral genes by inducing phosphorylation of the C-terminal domain (CTD) of RNA polymerase II (RNAPII). Tat can also disturb cellular metabolism by inhibiting proliferation of antigen-specific T lymphocytes and by inducing cellular apoptosis. Tat-induced apoptosis of T-cells is attributed, in part, to the distortion of microtubules polymerization. LIS1 is a microtubule-associated protein that facilitates microtubule polymerization.
