Recombinant HBV/Hepatitis B Virus Core (delta, aa 1-144)

HBV Core Delta protein although stable at 4C for 1 week, should be stored below -18C. Please prevent freeze thaw cycles.

Hepatitis B is one of a few known non-retrovira lviruses which employ reverse transcription as a part of its replication process. (HIV, a completely unrelated virus, also uses reverse transcription, but it is a retrovirus.) HBV invades the cell by binding to surface receptor and become internalized. The viral core particles then migrate to the hepatocyte nucleus and the partially double-stranded, relaxed circular genomes (RC-DNA) are repaired to form a covalently closed circular DNA (cccDNA), which is the template for viral genomic and sub-genomic RNAs by cellular RNA polymerase II. Of these, the pregenomic RNA (pgRNA is selectively packaged into progeny capsids and is then reverse-transcribed into new RC-DNA. The core can either bud into the endoplasmic reticulum to be enveloped or exported from the cell or recycled back into the genome for conversion to cccDNA. The, E. coli, derived 14 kDa recombinant protein contains the HBV core delta ayw immunodominant region amino acids 1-144.

Immunoreactive with sera HBV-infected individuals.
