The structure of human CD23 and its interactions with IgE and CD21 [PDF]

, 2005
The low-affinity immunoglobulin E ( IgE) receptor, CD23 ( Fc epsilon RII), binds both IgE and CD21 and, through these interactions, regulates the synthesis of IgE, the antibody isotype that mediates the allergic response.

Identification and expression of a murine cytomegalovirus early gene coding for an Fc receptor [PDF]

, 1994
Several herpesviruses, including cytomegalovirus, induce receptors for the Fc domain of murine immunoglobulin G (IgG) molecules. Viral genes coding for these receptors have been characterized only for alphaherpesviruses. In this report, we describe a new

Structural Basis for Enhanced HIV-1 Neutralization by a Dimeric Immunoglobulin G Form of the Glycan-Recognizing Antibody 2G12

Cell Reports, 2013
The human immunoglobulin G (IgG) 2G12 recognizes high-mannose carbohydrates on the HIV type 1 (HIV-1) envelope glycoprotein gp120. Its two antigen-binding fragments (Fabs) are intramolecularly domain exchanged, resulting in a rigid (Fab)2 unit including ...

Full-length recombinant antibodies from Escherichia coli: production, characterization, effector function (Fc) engineering, and clinical evaluation

mAbs, 2022
Although several antibody fragments and antibody fragment-fusion proteins produced in Escherichia coli (E. coli) are approved as therapeutics for various human diseases, a full-length monoclonal or a bispecific antibody produced in E.

Anti-immunoglobulin antibodies. III. Properties of sequential anti- idiotypic antibodies to heterologous anti-gamma globulins. Detection of reactivity of anti-idiotype antibodies with epitopes of Fc fragments (homobodies) and with epitopes and idiotopes (epibodies)

Journal of Experimental Medicine, 1982
Murine anti-V region antibodies against a human monoclonal protein Gl with anti-gamma-globulin activity and bearing the Wa cross-reactive idiotype were prepared in several strains of mice.

Intracellular Antibodies for Drug Discovery and as Drugs of the Future

Antibodies, 2023
The application of antibodies in cells was first shown in the early 1990s, and subsequently, the field of intracellular antibodies has expanded to encompass antibody fragments and their use in target validation and as engineered molecules that can be ...

Intrachain disulphide bridges in immunoglobulin G heavy chains. The Fc fragment [PDF]

Biochemical Journal, 1968
The disulphide bridges of the Fc fragment (C-terminal half of the heavy chain) have been studied in several human immunoglobulins, containing heavy chains of different antigenic types (γ1, γ2, γ3 and γ4), and in heavy-chain-disease proteins. Two intrachain disulphide bridges were found to be present.

Production of highly and broad-range specific monoclonal antibodies against hemagglutinin of H5-subtype avian influenza viruses and their differentiation by mass spectrometry

Virology Journal, 2018
Background The highly pathogenic avian influenza viruses of the H5 subtype, such as the H5N1 viral strains or the novel H5N8 and H5N2 reassortants, are of both veterinary and public health concern worldwide. To combat these viruses, monoclonal antibodies

A Fab-Selective Immunoglobulin-Binding Domain from Streptococcal Protein G with Improved Half-Life Extension Properties. [PDF]

PLoS ONE, 2015
Half-life extension strategies have gained increasing interest to improve the pharmacokinetic and pharmacodynamic properties of protein therapeutics. Recently, we established an immunoglobulin-binding domain (IgBD) from streptococcal protein G (SpGC3) as
