For in vitro use only!

Shipping: shipped on blue ice

Storage Conditions: store at -20 °C
avoid freeze/thaw cycles

Shelf Life: 12 months

Molecular Weight: 27 kDa

Purity: > 95 % (SDS-PAGE, RP-HPLC)

Form: liquid (Supplied in 10 mM NaPO4 pH 6.0, 0.1% SDS and 1 mM DTT)

Applications:
Antigen in ELISA and Western Blots. Excellent reagent for correct detection of HTLV infections with minimal specificity problems.

Description:
The 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 envelope amino acids 165 and ends with 440. The protein is purified by proprietary chromatographic technique.

Background: Human T-cell leukemia virus (HTLV)-1 and -2 are deltaretroviruses that infect a wide range of cells. HTLV-1 has been found primarily in CD4+ and CD8+ T-lymphocytes in vivo, whereas CD8+ T-lymphocytes are thought to be the in vivo reservoir of HTLV-2.

Specificity: Immunoreactive with all sera of HTLV-1 and HTLV-2 infected individuals with antibody response to HTLV envelope.
