Target description
Nuclear factor NF-kappa-B p105 subunit (UniProt: P19838; also known as DNA-binding factor KBF1, EBP-1, Nuclear factor of kappa light polypeptide gene enhancer in B-cells 1) is encoded by the NFKB1 gene (Gene ID: 4790) in human. NF- B family of transcription factors consists of five members in mammalian cells: NF-kB1 (p50/p105), NF-kB2 (p52/p100), RelA (p65), RelB, and c-Rel that associate to form various homodimeric or heterodimeric combinations. All members of NF-kB family share a highly conserved Rel homology domain (RHD), which is responsible for DNA binding, dimerization, and interaction with IkBs. The p50/RelA (p65) heterodimer is the major NF-kB complex in most cells. The p50 subunit of NF-kB (aa 1-433) is synthesized as a precursor molecule of 105 kDa (p105) (aa 1-968) and the subsequent processing of p105 releases the N-terminal p50 subunit that contains the Rel homology domain. The p50 subunit binds to the kappa-B consensus sequence 5′-GGRNNYYCC-3′, located in the enhancer region of genes involved in immune response and acute phase reactions. The carboxy-terminal region of p105 contains seven copies of an ankyrin-related sequence. The activity of NF-kB is tightly regulated by its interaction with inhibitory IkB proteins, which in most resting cells sequesters NF-kB in the cytoplasm in an inactive form. Unlike normal cells, in most cancer cells NF-kB is constitutively active and resides in the nucleus. Several key processes, such as self-sufficiency in growth signals, insensitivity to growth inhibitors, evading apoptosis, unlimited replicative potential, tissue invasion, and sustained angiogenesis, are all enhanced following NF-kB activation. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

С 2010 года мы поставляем оборудование с заводов Европы. Берем на себя все — от подбора оборудования до внедрения на предприятии

Все сотрудники имеют высшее образование, закончили ведущие химические вузы страны, такие как РХТУ им Менделеева.

У большинства компаний срок ожидания составляет 10-12 недель.

Оборудование хранится на сухом отапливаемом складе, где поддерживается ровная температура.

Работаем с PonyExpress и Деловыми линиями. Вы также можете выбрать свою транспортную компанию или забрать товар со склада в Москве.

В случае любых неполадок за свой счет выполним ремонт в сервисном центре или на заводе-изготовителе. Или бесплатно заменим прибор на новый.

Производим пуско-наладку оборудования, валидацию, обучение сотрудников. Если нужно, привлекаем инженеров с заводов- изготовителей.
