| Introduction | Human T-lymphotropic virus (HTLV) is a human, single-stranded RNA retrovirus that causes T-cell leukemia and T-cell lymphoma. The virus activates a subset of T-helper cellscalled Th1cells. The result is a proliferation of Th1 cells and overproduction of Th1 related cytokines (mainly IFN-gamma and TNF-alpha). Feedback mechanisms of these cytokines cause a suppression of the Th2 lymphocytes and a reduction of Th2 cytokine production (mainly IL-4, IL-5, IL-10 and IL-13). The end result is a reduction in the ability of the infected host to mount an adequate immune response to invading organisms that require a predominantly Th2 dependant response (these include parasitic infections and production of mucosal and humoral antibodies). |
| Description | The E.Coli derived recombinant protein contains the C- terminus of gp46 and most of p21E of HTLV-1. This non-fusion, E. coli-derived protein, starts from HIV-1 env. Amino acid 165, and is ending in amino acid 440, Mw 27 kDa. |
| Purification Method | HTLV-1 Envelope was purified by proprietary chromatographic technique. |
| Purity | HTLV-1 Envelope protein is >95% pure as determined by 10% PAGE (coomassie staining) and RP-HPLC. |
| Formulation | 10mM Na-PO4 pH 6.0, 0.1% SDS and 1mM DTT. |
| Solubility | It is recommended to reconstitute the lyophilized HTLV-1 Envelope in sterile 18M?-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized HTLV-1 Envelope although stable at room temperature for 3 weeks, should be stored desiccated below - 18°C. Upon reconstitution HTLV-1 Envelope 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. |
| Specificity | Immunoreactive with all sera of HTLV-I and HTLV-II infected individuals with antibody response to HTLV envelope. |
| Applications | HTLV-1 Envelope can be used as an antigen in ELISA and Western Blots. Excellent reagent for correct detection of HTLV infections, with minimal specificity problems. |
| Usage | ProSpecs products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
