由于NAR分子与Ig亚型在跨膜和分泌方式等几个功能特征方面近似,因此也被称为免疫球蛋白新抗原受体(Ig new antigen receptor,IgNAR)。 重链抗体具有广泛应用价值的是单域重链抗体(single domainantibody,sdAb)部分。单域重链抗体是指仅由重链抗体可变区(Variable region)组成的基因工程抗体,...
轻链的C区与V区均由β-sheet方式折叠成两团,对可变区氨基酸进行测序发现,其中某些区域的氨基酸基团可变程度远远高于周围,将这些区域称为超变区(hypervariable region, HV)三维结构上,这些超变区位于β-sheet的连接环(loop)处,由于它们与抗原结合,故被命名为互补决定区域(comp...
In particular, the present invention relates to recombinant monoclonal antibodies or fragments, including chimeric, primatized or humanized antibodies or fragments, having reduced effector function and altered ability to mediate cell signaling activity by a target antigen. In addition, the present ...

One immunotherapy strategy is using bi- and tri-specific NK cell engagers (BiKE and TriKE) to target the Fc gamma RIIIA/CD16a receptor with tumor-associated antigens to stimulate a cytotoxic response and mount an attack on tumor cells (6). CD16a is also capable of antibody dependent ...

region (1). NKp46 is expressed by activated and resting natural killer (NK) cells, innate lymphoid cell (ILC) 1, and a small population of T lymphocytes (1). NKp46, along with NKp30 and NKp44, are activating receptors that have been collectively termed the natural cytotoxicity receptors ...
Fab fragment antibodies are generated by papain digestion of whole IgG antibodies to remove the entire Fc portion, including the hinge region. These antibodies are monovalent, containing only a single antigen binding site. The molecular weight of Fab fragments is about 50 kDa. Usage Physical State...
No antibody was detected against non-immunoglobulin serum proteins. The antibody may cross-react with immunoglobulins from other species. Fab fragment antibodies are generated by papain digestion of whole IgG antibodies to remove the entire Fc portion, including the hinge region. These antibodies are...
antibody, usually expressed as one polypeptide chain with a linker in between the chains. Fab fragment is the variable domain of each chain, plus the first constant region. In the case of the Fab format, a linker is not essential because the CH1and CLregions will be fused by disulfide ...
