Introduction
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.

Description
HIV-1 TAT Clade-A Recombinant produced in E.coli is a single, non-glycosylated, polypeptide chain having the Accession number: AAL06113.1
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered and lyophilized, though might appear as a solution as a result of the glycerol content.
Formulation
Lyophilized with 10% glycerol.
Purity
Greater than 90.0% as determined by SDS-PAGE.
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
Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time.
Avoid multiple freeze-thaw cycles.
