| Introduction | Human immunodeficiency virus type-1 (HIV-1) regulatory Tat protein plays an crucial part in viral replication and infectivity. Throµghout acute infection, Tat protein is released extracellularly by infected cells and is taken up by neighboring cells where it transactivates viral replication and inhances 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. |
| Synonyms | NULL |
| Source | Escherichia Coli. |
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized with 0.1% glycerol. |
| Solubility | It is recommended to reconstitute the lyophilized HIV-1 TAT Cys 22 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 Cys22 althoµgh stable at room temperature for 1 week, should be stored desiccated below -18°C. Upon reconstitution HIV-1 TAT Cys22 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. |
| Purity | Greater than 90.0% as determined by SDS-PAGE. |
| Usage | NeoScientific's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drµgs, agricultural or pesticidal products, food additives or household chemicals. |
| Applications | Recognized by anti-Tat (HIV-1) polyclonal antibody. Reacts with anti-Tat antibodies from human, monkey, rabbit and mouse serum. |
| Specificity | Immunoreactive with all sera of HIV-1 infected individuals. |
