Elcatonin is a Calcitonin derivative which is transformed from eel ?s calcitonin by changing the S-S bond into the stable C-N bond. It inhibits the absorption and autolysis of bones, thus leads to blood calcium descending. In addition, it inhibits the bone salts dissolving and transferring and promotes the excretion of calcium and phosphorus in urine. Meanwhile, it inhibits renal tubules reabsorbing calcium, phosphorus and sodium and keeps blood calcium at normal level. It is mainly used for remitting or eliminating the pain caused by Osteoporosis. Elcatonin synthetic is a single, non-glycosylated polypeptide chain containing 31aa. Group: Biochemicals.

EPC play an important role in both angiogenesis and vasculogenesis. Recent evidence suggests the involvement of EPC in tumor growth and metastasis. Change in EPC number has been associated with lymphoma, multiple myeloma, Lewis lung tumor, and hepatocellular carcinoma (HCC). Alteration in EPC number and function has also been observed in pathogenesis of a variety of diseases including coronary artery disease (CAD), ischemia, pulmonary hypertension, cerebral vascular disease, acute myocardial infarction, diabetes mellitus, arthritis, and wound healing. In addition, EPC have impact on aging and smoking-related diseases, suggesting potential uses of EPC in thes Group: Biologicals. Grades: Molecular Biology Grade. Pack Sizes: 500K Cells.

Epothilone B (synthetic) (EpoB)
Epothilones are polyketide natural products that inhibit cancer cells by a mechanism similar to paclitaxel, and also are effective against paclitaxel-resistant tumors. Epothilone B is what is known as a microtubule stabilizer. When a cell divides, the chromosomes that will end up in each cell are separated by thin filaments called microtubules. Normally these microtubules then break down as the cell division progresses. This class of cytotoxic chemo drugs prevents that break down and thus prevents cells from completing division.
