Polyvalent interaction of antibodies with bacterial cells
Molecular Immunology, 1990We have studied the physical-chemical characteristics of the interaction of peroxidase-labelled rabbit antibodies with Bacillus sp. bacterial cells. The antibodies are able to bind bivalently with two antigen sites on the bacterial cells with the formation of intramolecular "cyclic" complexes.

Serum antibodies and bacterial meningitis
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1991The role of serum antibodies in bacterial meningitis and the human defence against it is reviewed. There is good evidence from animal and human studies in vitro and in vivo showing that serum antibodies to the capsular polysaccharide of the bacteria play a major role in protection, whereas antibodies to other cell surface components vary in protective ...

Enzymatic Antibody Modification by Bacterial Transglutaminase
2013Enzymatic posttranslational modification of proteins permits more precise control over conjugation site than chemical modification of reactive amino acid side chains. Ideally, protein modification by an enzyme yields completely homogeneous conjugates with improved properties for research or therapeutic use. As an example, we here provide a protocol for

Measuring Antibody Orientation at the Bacterial Surface
2016Many bacteria have the ability to interact with antibodies as a means to circumvent the immune response. This includes binding to the Fc portion of antibodies, effectively reversing the antibody orientation and thus decreasing the Fc-mediated immune signaling.

Antibody recognition of bacterial surfaces and extracellular polysaccharides
Current Opinion in Structural Biology, 2020Because of the ongoing increase in antibiotic-resistant microbes, new strategies such as therapeutic antibodies and effective vaccines are required. Bacterial carbohydrates are known to be particularly antigenic, and several monoclonal antibodies that target bacterial polysaccharides have been generated, with more in current development.

ANTIBODIES AS INDICATORS FOR BACTERIAL SURFACE STRUCTURES
Annual Review of Microbiology, 1956Antibodies have been used very extensively for the detection, isolation, and identification of the ceIJular components of bacteria. This work could be applied, however, only in part to an evaluation of the topography of immuno chemically defined components in the cellular architecture.

Expression of Single-Domain Antibodies in Bacterial Systems
2012In this chapter we describe in detail the current protocols that are used to express single-domain antibodies in bacteria. Bacteria are among the most common expression systems for expressing recombinant proteins. We present different approaches for carrying out periplasmic and cytoplasmic expression, as well as small-scale and large-scale expression ...

Immunoadsorbent for the Isolation of Bacterial Specific Antibodies
Journal of Bacteriology, 1967A new method is described for the isolation and purification of large quantities of bacterial specific antibodies. The technique involves the use of polymerized microorganisms as a specific immunoadsorbent. There should be wide application of this method for the purification of antibodies to various types of microorganisms, provided that the ...

Antibody responses to bacterial antigens in the pregnant ewe
New Zealand Veterinary Journal, 1986The humoral immune response to the novel antigen Brucella abortus (S19) was examined in nonpregnant ewes and in ewes at different stages of pregnancy. Both the primary and secondary responses were monitored, by measuring the levels of total antibody, Immunoglobulin G (IgG), and complement fixing antibody.
