Molybdenum (Mo)
Recognized as a new element in 1778, the first impure form of molybdenum was produced in 1782.
The metal is silvery white and very hard, although softer and more ductile than tungsten. Used as an alloying agent, it makes quenched and tempered steels both harder and tougher and improves their strength at high temperatures. Molybdenum oxidizes at elevated temperatures.
It is used in nickel-based alloys that are heat and corrosion-resistant. The metal has been used for electrically heated glass furnace and fore hearth electrodes, in nuclear energy applications, and in aircraft and missile parts.
Molybdenum is an essential trace element for nitrogen fixation and other metabolic processes.

Sigma Aldrich Fine Chemicals Biosciences TeloTAGGGTM Telomere Lengt
The kit utilizes Southern analysis of terminal restriction fragments (TRf) that are obtained by the digestion of genomic DNA using frequently cutting restriction enzymes.Step 1 Digestion of genomic DNAPurified genomic DNA is digested by an optimized mixture of frequently cutting restriction enzymes. The enzymes have been selected in such a way that telomeric DNA and sub-telomeric DNA is not cut. This is due to the special sequence characteristics of the repeats. Non-telomeric DNA is digested to low molecular-weight fragments.Step 2 Gel electrophoresis and Southern blottingfollowing DNA digestion the DNA fragments are separated by gel electrophoresis then transferred to a nylon membrane by Southern blotting.Step 3 Hybridization and chemiluminescence detectionThe blotted DNA fragments are hybridized to a digoxigenin (DIG)-labeled probe that is specific for telomeric repeats then incubated with a DIG-specific antibody covalently coupled to alkaline phosphatase. finally the immobilized
