U-Blot® TWIST Recombinant Antibody

Background:AbFlex ® antibodies are recombinant antibodies (rAbs) that have been generated using defined DNA sequences to produce highly specific, reproducible antibodies. Each AbFlex antibody contains a 6xHis Tag, a Biotinylation Tag for enzymatic biotin conjugation using the biotin ligase, BirA, and a sortase recognition motif (LPXTG) to attach a variety of labels directly to the antibody including fluorophores, enzymatic substrates (HRP, AP), peptides, drugs as well as solid supports. AbFlex ® TWIST antibody was expressed in was expressed as full-length IgG with mouse immunoglobulin heavy and light chains (IgG2a isotype) in mammalian 293 cells. TWIST is a regulator of transcription that serves as a master regulator of embryonic morphogenesis. Through its bHLH motif it interacts with many different transcription factors to affect multiple pathways of gene expression. TWIST plays a pivotal role in mesodermal, myoblast, and osteoblast differentiation. TWIST is involved in the epithelial–mesenchymal transition (EMT), a period during embryonic development characterized by loss of cell adhesion and increased cell mobility, essential events for mesoderm and neural tube formation. The EMT shares many features of metastatic cancer, and elevated levels of TWIST are observed in many types of cancer. Mutations in the gene encoding TWIST have been associated with Saethre-Chotzen syndrome, an inherited developmental disorder characterized by skull deformations, limb abnormalities, and facial dysmorphisim.
