Descrizione del bersaglio

Twist-related protein 1 (UniProt: Q15672; also known as Class A basic helix-loop-helix protein 38, bHLHa38, H-twist) is encoded by the TWIST1 (also known as BHLHA38, TWIST) gene (Gene ID: 7291) in human. TWIST1 is a basic helix-loop-helix (bHLH) domain (aa 108-159) containing transcription factor with two nuclear localization sequences (aa 37-40 and 73-77). It can form homodimers or heterodimers in order to bind the Nde E-box element and activate or repress its target genes. It is shown to inhibit myogenesis by sequestrating E proteins. TWIST1 is also reported to represses expression of proinflammatory cytokines such as TNF-a and IL-1b. During development, it is shown to be essential for mesoderm specification and differentiation. It promotes EMT in part by directly repressing E-cadherin expression by recruiting the nucleosome remodeling and deacetylase complex for gene repression and by upregulating Bmi1, AKT2, and YB-1. TWIST1 stability is regulated by phosphorylation of serine 68 by MAP kinases (p38, JNK, and ERK1/2). This phosphorylation prevents ubiquitination-mediated degradation of TWIST1. Heterozygous loss-of-function mutations of the human Twist1 gene is shown to cause several diseases including the Saethre-Chotzen syndrome and Robinow-Sorauf syndrome. Twist1-null mouse embryos die with unclosed cranial neural tubes and defective head mesenchyme, somites and limb buds. TWIST1 expression is also observed in many types of aggressive tumors, including breast cancer, hepatocellular carcinoma, prostate cancer, pancreatic cancer, and esophageal squamous cell carcinoma. It can override oncogene-induced cell senescence and apoptosis and can increase cancer cell resistance to chemotherapeutic agents. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Stato fisico

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Ricostituzione

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Stoccaggio e stabilità

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
