Popis: The MXPC SERIES comes from the latest generation of Welch MPCpro diaphragm pumps to provide improved performance, particularly in the application critical range. The ultimate vacuum of 5 or 1,5 mbar with significant design improvements to directly influence the process flow and the repeatability. The new Single Piece Diaphragm (SPD) design provides increased chemical resistance and easier servicing. These models are ideal for applications where a high pumping speed, fast pump down time and deep ultimate vacuum are required, such as vacuum ovens, rotary evaporators and vacuum concentrators.

Popis: These non-chemical-resistant diaphragm pumps characterized by a compact design, long lifespan and oil-free evacuation are designed for aqueous and standard duty applications. The diaphragm series are well known for smooth operation. They are available in one or multistage configuration with controlled (ecoflex) or uncontrolled pumping speed. Ecoflex diaphragm pumps are equipped with a state-of-the-art vacuum control which allows the pumping speed to be varied.

Popis: The MPC chemical duty diaphragm pumps use PTFE and other fluorinated plastics for the wetted parts to allow aggressive solvent and acid vapours to be pumped. If the pump should handle harsh chemical vapours, then the superior chemical resistant X2 version with higher grade seals and thicker coatings are the best choice. These are well known for quiet operation and running smoothness.

Popis: The adenomatous polyposis syndromes, familial adenomatous polyposis (FAP) and Gardner's syndrome (GS), are characterised by numerous adenomatous polyps throughout the entire colon. These polyps invariably progress to colon cancer in addition to other extracolonic manifestations. The cloning of the APC gene revealed a ubiquitously expressed protein, 2843 amino acids in length, which is frequently mutated in patients suffering from FAP and GS. APC has been found to be associated with structural components of intracellular junctions. b-catenin and g-catenin (also called plakoglobin) are involved in the regulation of cellular adhesion. APC and E cadherin compete for binding to specific internal regions of both b- and g-catenin. Interactions between cytoskeleton and the APC, E cadherin, b/g catenin complex are mediated by a-catenin.

Popis: Src is the human homolog of the v-Src gene of the rous sarcoma virus, also designated avian sarcoma virus or ASV. Src was the first proto-oncogenic non-receptor tyrosine kinase characterized in human. The Src family, which has common structural motifs, is composed of nine members in vertebrates, including Src, Yes, Fgr, Frk, Fyn, Lyn, Hck, Lck and Blk. Src-family kinases transduce signals that are involved in the control of a variety of cellular processes, including proliferation, differentiation, motility and adhesion. Src-family ki-nases contain an amino-terminal cell membrane anchor followed by an SH3 domain and an SH2 domain, which are involved in modular association and activation, respectively. Src-family kinases, which are normally maintained in an inactive state and can be activated transiently during cellular events such as mitosis. Different subcellular localizations of Src-family kinases may be important for the regulation of specific cellular processes such as mitogenesis, cytoskeletal organization and membrane trafficking. c-Fgr is a human non-receptor tyrosine kinase family member that was discovered by using a probe toward the v-Fgr portion of the cell-derived domain of Gardner-Rasheed feline sarcoma virus. The human c-Fgr gene encodes a 529 amino acid protein.
