Antibodies are a class of biomolecules that has an important role in the immune system and lots of applications in biotechnological methods and in pharmaceutics. Production and purification of antibodies in laboratory animals is one of the first ways to manufacture of these prominent tools. The obtained antibodies from these process could be used in various types of bioassay techniques such as ...
Evidence of antibody isotype/subtype switching may provide prognostic value regarding the state of immune responses to therapeutic proteins, e.g. anti-factor VIII (FVIII) antibodies that develop in many hemophilia A patients, clinically termed "inhibitors". A sensitive, high- information-content surface plasmon resonance (SPR) assay has been developed to quantify IgG subtype distributions and t...
background: dna vaccines are third generation vaccines which have made promises to combat infectious diseases. cationic liposomes are used as effective delivery systems for dna vaccines to generate stronger immunity. objective: encapsulation of pcdna3.1+pa plasmid, encoding protective antigen (pa) of bacillus anthracis (b. anthracis) into cationic liposomes, and evaluation of its effect on spec...
Stable aggregated IgG (A-IgG) of various sizes, having high biological activity, were incubated at 4 degree C with adhering peritoneal macrophages from normal rats and the kinetics of A-IgG binding to the cell surface were studied. Equilibrium constants were high (2.8-11.7 X 10(8) M-1) and varied as a function of aggregate size. The maximum number of A-IgG bound per cell varied from 230,000 for...
BACKGROUND The role of specific IgG(4) antibodies in natural tolerance acquisition remains a matter of debate; the specific IgE/IgG(4) ratio might add value to the measurement of absolute amounts of IgE for assessing the ongoing status of egg reactivity. OBJECTIVE We sought to determine the significance of IgG(4) antibodies to ovalbumin (OVA) and ovomucoid (OVM) in egg-allergic children. ME...
Group B streptococci (GBS; Streptococcus agalactiae) are the most common cause of neonatal sepsis and meningitis. Serotype-specific IgG antibody is known to protect neonates against GBS infections by promoting opsonophagocytosis. The L-ficolin-mediated lectin pathway of the complement is also a potential mechanism for opsonization of GBS, because L-ficolin activates the complement after binding...
Abstract Virus-specific neutralizing antibodies are generally accepted as a correlate of protection against infection, though many questions remain about which components the immune response protect SARS-CoV-2 infection. We longitudinally measured Spike receptor binding domain (RBD)-specific serum IgG and nucleocapsid protein (NP)-specific in human cohort immunized with Pfizer BNT162b2 vaccine....
