Optimized DNA sequence encoding Human Natural Killer Cell Receptor NKp44 (GLN22 - PRO190) extracellular domain including a C-terminal His tag was expressed in HEK293 cells.
Recombinant Human Natural Killer Cell Receptor (NCR2) is a protein consisting of 176 amino acid residue subunits,due to glycosylation migrates as an approximately as 35kDa band protein on reduced SDS-PAGE.
>95%, as determined by SDS-PAGE and HPLC
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/Âµg(1EU/Âµg).
Recombinant human NKp44 is lyophilized Â from 0.2 Î¼m filtered PBS solution, Â pH7.2 , Â 5% Trehalose.

The natural cytotoxicity
receptors are a unique set
of activating proteins
expressed mainly on the
surface of natural killer
(NK) cells. The human
receptor family comprises
the three type I membrane
proteins NKp30, NKp44, and
NKp46. NKp44 is expressed
only on activated NK cells
and was reported to be
involved in triggering NK
cells’ cytolytic activity
