Manufacturability and functionality assessment of different formats of T-cell engaging bispecific antibodies

mAbs, 2023
T-cell-engaging bispecific antibodies (T-bsAbs) are promising immunotherapies for cancer treatment due to their capability of redirecting T-cells toward destroying tumor cells.

Enzymic degradation of the Fc fragment of rabbit immunoglobulin IgG [PDF]

Biochemical Journal, 1967
The digestion of the Fc fragment of rabbit immunoglobulin IgG by several proteolytic enzymes was investigated by using gel filtration and starch-gel electrophoresis in 8m-urea-formate as criteria of the extent of degradation. Though fragment Fc and mildly reduced fragment Fc proved resistant to tryptic hydrolysis, papain and pepsin cleaved the fragment

Activating FcγR function depends on endosomal-signaling platforms

iScience, 2023
Summary: Cell surface receptor internalization can either terminate signaling or activate alternative endosomal signaling pathways. We investigated here whether endosomal signaling is involved in the function of the human receptors for Fc immunoglobulin ...

Immunoglobulin Fc heterodimer platform technology: From design to applications in therapeutic antibodies and proteins

Frontiers in Immunology, 2016
The monospecific and bivalent characteristics of naturally occurring immunoglobulin G (IgG) antibodies depend on homodimerization of the fragment crystallizable (Fc) regions of two identical heavy chains (HCs) and the subsequent assembly of two identical

Fc-Galactosylation of Human Immunoglobulin Gamma Isotypes Improves C1q Binding and Enhances Complement-Dependent Cytotoxicity

Frontiers in Immunology, 2017
Binding of the complement component C1q to the CH2 domain of antigen-bound immunoglobulin gamma (IgG) activates the classical complement pathway and depends on its close proximity to Fc fragments of neighboring antibodies. IgG subclasses contain a highly

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.

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 ...

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 ...

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
