Quadrigen (DPT combined with the Salk polio vaccine) – random notes
In 1959, the Parke-Davis Quadrigen vaccine (DPT combined with the Salk polio vaccine) is licensed. The vaccine is alleged to be particularly reactive because of the effect of the preservative on the pertussis component. Several lawsuits ensue. The vaccine is withdrawn from the market in 1968 (Coulter and Fisher, 1985). Institute of Medicine (US) Committee…

The molecular mayhem of immunogens, haptens, carriers and adjuvants
First up, the immunogen: the molecular maestro of the immune system, orchestrating a symphony of B-cells and T-cells like a conductor with a grudge. These substances don’t just knock politely on the immune system’s door—they kick it down with the force of a battering ram. Immunogens are a subset of antigens (because “antibody-generating” wasn’t obvious enough)…

The Membrane Attack Complex/Perforin (MACPF) superfamily aka MACPF/CDC superfamily
See also: Complement membrane attack complex The Membrane Attack Complex/Perforin (MACPF) superfamily, sometimes referred to as the MACPF/CDC superfamily, is named after a domain that is common to the membrane attack complex (MAC) proteins of the complement system (C6, C7, C8α, C8β and C9) and perforin (PF). Members of this protein family are pore-forming toxins (PFTs). In eukaryotes, MACPF proteins play a role in immunity and development. Archetypal members of the family…

The membrane attack complex (MAC) or terminal complement complex (TCC) is a complex of proteins typically formed on the surface of pathogen cell membranes as a result of the activation of the host’s complement system, and as such is an effector of the immune system
From Wikipedia, the free encyclopedia See also: MACPF The membrane attack complex (MAC) or terminal complement complex (TCC) is a complex of proteins typically formed on the surface of pathogen cell membranes as a result of the activation of the host’s complement system, and as such is an effector of the immune system. Antibody-mediated complement activation leads to MAC deposition on the surface of infected cells. Assembly…

What is Immunoprecipitation (IP)?
Immunoprecipitation (IP) is a technique used to enrich protein antigens from a complex mixture using specific antibodies. To carry out an IP, antibodies must be coupled to a solid substrate, such as agarose resin or magnetic beads, to allow for purification of the target antigens. Immunoprecipitation (IP) is the technique of precipitating a protein antigen out of solution using an antibody that…
