Target description

Tyrosine-protein kinase JAK2 (UniProt: O60674; also known as EC:2.7.10.2, Janus kinase 2, JAK-2) is encoded by the JAK2 gene (Gene ID: 3717) in human. The Janus kinase (JAK)/signal transducers and activators of transcription (STAT) signaling pathway play an important role in cell proliferation, cell differentiation, cell migration, and cell death. It is the principal signaling mechanism for a variety of cytokines and growth factors. JAK/STAT signaling is also involved in hematopoietic development. Constitutive activation or dysregulation of JAK/STAT signaling can result in inflammatory disease, erythrocytosis, gigantism, and leukemia. In mammals, the JAK family is composed of four members: JAK1, JAK2, JAK 3, and Tyk2. JAK2 is a non-receptor tyrosine kinase that mediates essential signaling events in both innate and adaptive immunity. It contains two protein kinase domains (aa 545-809 and 849-1124). Its catalytic activity is assigned to the second kinase domain. In the cytoplasm, it plays a pivotal role in signal transduction via its association with type I receptors such as growth hormone (GHR), prolactin (PRLR), leptin (LEPR), erythropoietin (EPOR), thrombopoietin (THPO); or type II receptors including IFN-a, IFN-b, IFN-g, and multiple interleukins. Following ligand-binding to cell surface receptors, it phosphorylates specific tyrosine residues on the cytoplasmic tails of the receptor, creating docking sites for STATs proteins. Subsequently, it phosphorylates the STATs proteins recruited to the receptor. Phosphorylated STATs then form homodimer or heterodimers and translocate to the nucleus to activate gene transcription. In the nucleus, JAK2 regulates transcription by specifically phosphorylating Tyr-41 of histone H3 (H3Y41ph), a specific tag that promotes exclusion of CBX5 from chromatin. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

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.

Reconstitution

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.

Storage and Stability

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.
