Description

The generation of the CD44 recombinant monoclonal antibody relies on in vitro expression systems, which are established by cloning the DNA sequences of CD44 antibodies from immunoreactive rabbits. The immunogen employed in this process is a synthesized peptide derived from the human CD44 protein. Subsequently, the genes encoding the CD44 antibodies are inserted into plasmid vectors, and these recombinant plasmid vectors are then transfected into host cells to facilitate antibody expression. Following expression, the CD44 recombinant monoclonal antibody undergoes affinity-chromatography purification and is thoroughly tested for functionality in ELISA, WB, IHC, IF, and FC applications, confirming its reactivity with the human CD44 protein.

CD44 is a versatile cell surface glycoprotein with numerous functions in cell adhesion, migration, signaling, and immune responses. Its roles extend to various physiological processes and pathological conditions, including inflammation, cancer, tissue development, and stem cell regulation.

Target Background

Function
Cell-surface receptor that plays a role in cell-cell interactions, cell adhesion and migration, helping them to sense and respond to changes in the tissue microenvironment. Participates thereby in a wide variety of cellular functions including the activation, recirculation and homing of T-lymphocytes, hematopoiesis, inflammation and response to bacterial infection. Engages, through its ectodomain, extracellular matrix components such as hyaluronan/HA, collagen, growth factors, cytokines or proteases and serves as a platform for signal transduction by assembling, via its cytoplasmic domain, protein complexes containing receptor kinases and membrane proteases. Such effectors include PKN2, the RhoGTPases RAC1 and RHOA, Rho-kinases and phospholipase C that coordinate signaling pathways promoting calcium mobilization and actin-mediated cytoskeleton reorganization essential for cell migration and adhesion.
