Ammonium sulfide 20% in aqueous solution

Supplier: MP Biomedicals

Description: Ammonium sulfide solution (aqueous ammonium sulfide) is a 20% solution in water. Ammonium sulfide is an inorganic salt with a sulfurous odor, which is commonly used in the food industry as a flavoring agent. The influence of ammonium sulfide treatment on (100)GaAs (gallium arsenide) surfaces has been studied by X-ray photoelectron spectroscopy (XPS) and reflection high-energy electron diffraction (RHEED). Its potential as an alternative to hydrogen sulfide for the transformation of activated amides to thioamides by thiolysis has been investigated.The reaction of ammonium sulfide with 3-hydroxy-2-butanone over a range of temperature has been reported to form various flavor compounds.

Dimethyl sulfoxide for molecular biology

Supplier: MP Biomedicals

Description: Storage: Room Temperature, desiccate, store under nitrogen.
Dimethyl Sulfoxide is a dipola, aprotic solvent. It has been shown to accelerate strand renaturation (1-10% concentration) and is believed to give the nucleic acid thermal stability against depurination.
Dimethyl Sulfoxide is used to enhance dermal absorption of many chemicals, as a solvent for many organic and inorganic compounds including fats, carbohydrates, dyes, resins, and polymers, in antifreeze or hydraulic fluids, as a cryopreservative for cell cultures, oxidation of thiols and disulfides to sulfonic acids, as a PCR cosolvent to help improve yields, especially in long PCR. DMSO is routinely used in polymerase chan reaction (PCR), amplification of cDNA libraries, DNA sequencing, column-loading buffers for poly (A)+ RNA selection, buffers for the transformation of competent E. coli, and transfection protocols.
To prepare sterile solutions use a teflon or nylon membrane to sterile-filter the DMSO - do not use a cellulose acetate membrane.

Dimethyl sulfoxide ≥99% cell culture reagent

Supplier: MP Biomedicals

Description: Dimethyl Sulfoxide is ideal for use as a cryoprotectant. Also used in chemical reactions, in polymerase chain reactions (PCR) as a PCR cosolvent to help improve yields, especially in long PCR, and as a cryoprotectant vitrification agent for the preservation of cells, tissues and organs. DMSO is used in cell freezing media to protect cells from ice crystal-induced mechanical injury. It is used for frozen storage of primary, sub-cultured, and recombinant heteroploid and hybridoma cell lines, embryonic stem cells (ESC), and hematopoietic stem cells. DMSO is frequently used in the combinations with BSA or fetal bovine serum (FBS). Used to enhance dermal absorption of many chemicals. A solvent for many organic and inorganic compounds including fats, carbohydrates, dyes, resins, and polymers. Used in antifreeze or hydraulic fluids. A cryopreservative for cell cultures. Used in the oxidation of thiols and disulfides to sulfonic acids.
