  • 产品描述：

    The first step in the preparation of recombinant ISL1 antibody is to obtain the ISL1 antibody gene. The heavy and light chain genes of the antibody were constructed into a plasma vector and then transfected into suspended mammalian cells transiently. After expression verification, cell supernatant was collected in expanded culture and purified recombinant ISL1 antibody was obtained using affinity-chromatography. This recombinant ISL1 antibody has been validated for the detection of ISL1 protein from Human in the ELISA, WB.

    ISL1 is a LIM-homeodomain transcriptional factor that marks undifferentiated cardiac progenitors of the second heart field and is required for these progenitors to contribute to the heart. ISL1 participates in multiple cellular processes, such as islet cell differentiation, motor neuron generation, as well as cardiovascular development. In embryonic and postnatal pancreatic islets, ISL1 is essential for facilitating pancreatic islets proliferation and maintaining endocrine cells survival. It also plays a key role in multiple organs during embryonic development.

  • 功能：
    DNA-binding transcriptional activator. Recognizes and binds to the consensus octamer binding site 5'-ATAATTAA-3' in promoter of target genes. Plays a fundamental role in the gene regulatory network essential for retinal ganglion cell (RGC) differentiation. Cooperates with the transcription factor POU4F2 to achieve maximal levels of expression of RGC target genes and RGC fate specification in the developing retina. Involved in the specification of motor neurons in cooperation with LHX3 and LDB1. Binds to insulin gene enhancer sequences. Essential for heart development. Marker of one progenitor cell population that give rise to the outflow tract, right ventricle, a subset of left ventricular cells, and a large number of atrial cells as well, its function is required for these progenitors to contribute to the heart. Controls the expression of FGF and BMP growth factors in this cell population and is required for proliferation and survival of cells within pharyngeal foregut endoderm and adjacent splanchnic mesoderm as well as for migration of cardiac progenitors into the heart.
