abstract = {The grass carp (Ctenopharyngodon idellus) PKZ full-length
cDNA (GU299765) had been cloned and identified recently. Within its N-terminal
part of the protein there are two Z-DNA binding domains called Zα1 (1~67aa)
and Zα2 (81~152aa). Zα domain is unique to PKZ and distinguishes them
from other translation Initiation Factor 2 alpha (eIF2α)-kinase. To obtain
polyclonal antibody against CiPKZ Zα, the PKZ Zα gene was amplified
by PCR from the template obtained in the earlier research and identified by
DNA sequence analysis. Then, it was digested by BamHI, XhoI and ligated with
pET-32a vector which was by the same treatment. Sequenced and blasted with the
NCBI GenBank, the recombinant plasmid pET-32a-PKZ Zα was obtained. The
recombinant plasmid was transformed into E. coli BL21 (DE3) and induced
by 1 mmol L-1 IPTG. Researchers obtained CiPKZ Zα polypeptide
via E. coli prokaryotic expression and purified with Ni-NTA His-Bind
Resin affinity chromatography. Rabbit Polyclonal Antibody (Pab) against CiPKZ
was raised using the purified N-terminal fragment of CiPKZ containing its Zα1
and Zα2 domains. Western blot analysis showed that the antibody had high
affinity and specificity and higher titer. Immunohistochemistry assay identified
that expression of PKZ could be detected in liver tissue.}
