A bispecific monoclonal antibody (BsMAb, BsAb) is an artificial protein that can simultaneously bind to two different types of antigen or two different epitopes on the same antigen. [1] Naturally occurring antibodies typically only target one antigen. BsAbs can be manufactured in several structural formats.
Psychology Today is an American media organization with a focus on psychology and human behavior. The publication began as a bimonthly magazine, which first appeared in 1967. The print magazine's reported circulation is 275,000 as of 2023. [ 2 ]
Crystal structure of PCSK9 (28]PCSK9 is a member of the peptidase S8 family. [27]: Family & Domains The solved structure of PCSK9 reveals four major components in the pre-processed protein: the signal peptide (residues 1-30); the N-terminal prodomain (residues 31–152); the catalytic domain (residues 153–425); and the C-terminal domain (residues 426–692), which is further divided into ...

The specific nature of the antibody-antigen interaction is analogous to a lock and key fit in that the antigen will only bind to the antibody if it has the correct conformation. Binding events result in a physicochemical change that in combination with a tracer, such as fluorescent molecules, enzymes, or radioisotopes, can generate a signal.
This became the standard method, still used today, for graft allocation. With PRA that identifies several antibodies to a potential cluster of donors, the crossmatch will identify if a recipient had antibodies to a specific donor of interest. It became clear with time that it did not identify all preexisting donor-specific HLA antibodies (HLA-DSA).
Passive antibody administration has become a widely approved cancer treatment following the development of monoclonal antibody (mAb). Since these antibodies originated from mice, they were wrought with problems of immunogenetics and poor abilities to induce an immune response in the human body, limiting their clinical applicability.

Theoretical psychology has many aspects that can be viewed as positive or negative, which depends on the interpreter. Theoretical psychology can play an important and also unique role in the field such that almost any claim can be reasonably thought of as true if it is theoretically appealing and empirically supported by research.
