简单介绍：
HTLV-1 Envelope
详情介绍：
Catalogue number
HIV-107
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 HTLV-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.
Physical Appearance
Sterile filtered colorless solution.
Formulation
10mM Na-PO4 pH 6.0, 0.1% SDS and 1mM DTT.
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.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.

Purity
HTLV-1 Envelope protein is >95% pure as determined by 10% PAGE (coomassie staining) and RP-HPLC.
Specificity
Immunoreactive with all sera of HTLV-I and HTLV-II infected individuals with antibody response to HTLV envelope.
