Recombinant Proteins<br />

206<br />

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 />

HIV-1 Nef protein (full length,<br />

myr2-210) His , myristoylated<br />

Recombinant, E. coli<br />

Cat. No. Amount Price (€)<br />

PR-382 50 µg 200,--<br />

Liquid. Supplied in 10 mM Tris-HCl, pH 7.8, 50 mM<br />

NaCl and 2 mM DTE.<br />

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

protein (myr2-210, C210S, SF2 strain) with a<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 />
