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.

Alkali Scientific TES, Sodium Salt, [2 Tris(hydroxymethyl) methyl 2 amino 1 ethanesulfonic acid, sodium salt], 25 Grams
TES (Tris(hydroxymethyl) methyl 2-amino-1-ethanesulfonic acid), Sodium Salt, is a high-purity buffering agent commonly used in laboratory settings for maintaining stable pH levels during biochemical reactions. The 25g size is ideal for preparing small to medium quantities of buffer solutions, especially for protein studies, electrophoresis, and enzyme assays. TES buffers are known for their low absorbance in UV spectrophotometry, making them an excellent choice for spectrophotometric assays. The high purity ensures that TES does not interfere with sensitive experimental conditions, providing consistent and reliable results in research and diagnostic applications.

Hach Company HQ440D Laboratory pH Meter Package for Dirty Samples with Fast Response RedRod PHC735 Glass Refill Electrode
Designed for water quality experts, the Hach HQ440D Laboratory Multi-Meter is an advanced laboratory meter that takes the guesswork out of measurements. HQD digital meters connect with smart Intellical electrodes that automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time. The advanced HQD Laboratory Meter is designed to withstand years of continuous lab use. HQD bench meters feature a simple user interface that does not require manuals or training to operate. The Intellical PHC735 is a digital, combination glass-body electrode with a refillable KCl reference and built-in temperature sensor. The PHC735 utilizes Red Rod technology to deliver exceptionally fast response times and stable, accurate measurements. It has a high-flow annular ring junction and is ideal for measuring pH of “dirty” samples, including wastewater and food and beverage applications.
Sigma Aldrich Fine Chemicals Biosciences Cas9 GFP Lentiviral Partic
Ready-to-use Cas9-GFP lentiviral particles enable immediate transduction of a wide range of cell lines. Cas9-GFP lentiviral particles efficiently and stably integrate Cas9 and GFP linked by a 2A peptide and driven by the EF1 alpha promoter (EF1a-Cas9-2A-GFP) for strong expression in both dividing and non-dividing cell lines. They are ideal for avoiding the tedious lentivirus production process and are one part of a two part CRISPR system with individual Cas9 and gRNA expression vectors. For easy fluorescence microscopy a MOI greater than 200 should be employed. To order gRNA in any format click here
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
