Anti-MITF, clone 1E2 ZooMAb^®, Cat. No. ZRB1335, is a recombinant Rabbit monoclonal antibody that specifically targets MITF and is tested for use in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry, and Western Blotting.

Microphthalmia-associated transcription factor (UniProt: O75030; also known as Class E basic helix-loop-helix protein 32, bHLHe32, MITF) is encoded by the MITF (also known as BHLHE32) gene (Gene ID: 4286) in human. MITF is a transcription factor that regulates the expression of genes with essential roles in cell differentiation, proliferation, and survival. It is expressed in kidney and melanocytes. Isoforms C2, H1 and H2 are mainly expressed in kidney and isoforms M1 and Mdel are expressed in melanocytes. Isoforms A2 and C2 are detected in retinal pigment epithelium. It is present in homodimeric or heterodimeric form. Its dimerization is mediated via the coiled coil region (aa 355-402). Its efficient DNA binding requires dimerization with another bHLH protein. It binds to M-boxes (5′-TCATGTG-3′) and symmetrical DNA sequences (E-boxes) (5′-CACGTG-3′) found in the promoters of target genes, such as BCL2 and tyrosinase (TYR). MITF plays an important role in melanocyte development by regulating the expression of TYR and tyrosinase-related protein 1 (TYRP1). It also plays a critical role in the differentiation of various cell types, such as neural crest-derived melanocytes, mast cells, osteoclasts, and optic cup-derived retinal pigment epithelium. It can undergo phosphorylation at serine 405, which enhances its ability to bind the tyrosinase promoter. Its phosphorylation at serine 180 and serine 516 following KIT signaling, trigger a short-lived activation. These phosphorylations by MAPK and RPS6KA1, respectively, activate the transcription factor activity, but also promote ubiquitination and subsequent degradation by the proteasome. Mutations in MITF gene have been linked to cutaneous malignant melanoma and Waardenburg syndrome 2A, which is characterized by sensorineural deafness and pigmentary disturbances. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 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.

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.

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.
