HIV-1 Nef protein<br />
(full length, 1-210) His<br />
Recombinant, E. coli<br />
Cat. No. Amount Price (€)<br />
PR-381 50 µg 200,--<br />
Liquid. Supplied as ca. 1 mg/ml solution in PBS.<br />
Recombinant N-terminal His-tagged full-length HIV-1<br />
Nef protein (SF2 strain).<br />
Human immunodefi ciency virus type 1 (HIV-1) Nef<br />
is a membrane-associated protein that is produced<br />
at the earliest stage of viral gene expression and<br />
is a component of viral particles. Nef has been<br />
demonstrated to bind and downregulate cell-surface<br />
receptors CD4 and MHC I. In addition, Nef has been<br />
reported to have diverse effects on cellular signal<br />
transduction pathways. It interacts with various cellular<br />
protein kinases and acts both as a kinase substrate<br />
and as a modulator of kinase activity.<br />
Purity: 90% by SDS-PAGE.<br />
Store: 4 °C<br />

Recombinant myristoylated full-length HIV-1 Nef<br />

C-terminal His-tag. Runs on SDS-PAGE at 33 kD.<br />
Human immunodefi ciency virus type 1 (HIV-1) Nef is<br />
a membrane-associated protein that is produced at an<br />
early stage of viral gene expression and is a component<br />
of viral particles. Nef has been demonstrated to bind<br />
and downregulate cell-surface receptors CD4, MHC<br />
class I and II molecules and DC-SIGN. A Nef mutant<br />
with simple alanine substitutions at the myristoylation<br />
and dileucine sites was impaired in its ability to elicit<br />
Nef-specifi c CD4(+) and CD8(+) T cell responses.<br />
In addition, Nef has been reported to have diverse<br />
effects on cellular signal transduction pathways. It<br />
interacts with various cellular protein kinases and<br />
acts both as a kinase substrate and as a modulator<br />
of kinase activity.<br />
Purity: > 95% by SDS-PAGE.<br />
Store: -80°C<br />

HIV-2 RT<br />
Recombinant, E. coli<br />
Cat. No. Amount Price (€)<br />
PR-352 10 µg 220,--<br />
Liquid. Supplied as 1 mg/ml solution in 20 mM Tris-<br />
HCl, pH 7.8, 1 mM DTT, 1 mM EDTA, 15% glycerol,<br />
and 0.2% BSA.<br />
HIV-2 Reverse Transcriptase (RT) is used by the<br />
Human Immunodefi ciency Virus-1 to transcribe its<br />
RNA genome into single-stranded DNA. HIV-2 RT<br />
can be used for incorporation of nucleotide analogs<br />
into DNA by RT-PCR or as a standard for assaying<br />
HIV-2 RT activity in human serum. In contrast to<br />
HIV-1 RT, HIV-2 RT is not inhibited by non-nucleoside<br />
RT inhibitors (NNRTI´s).<br />
Purity: > 95% by SDS-PAGE.<br />
Activity: 10.000 U/mg (1 unit is defi ned as the amount<br />
of enzyme that incorporates 1 nmol of dTTP into acidinsoluble<br />
products in 10 min at 37°C)<br />
