Catalog Number: (100504-350)
Supplier: Electron Microscopy Sciences
Description: Similar to grease type L, but it contains more wax. Grease M has an estimated vapor pressure at 20°C of 2x10-9 torr, higher than Type L. Type M is recommended for applications where a grease of moderately low vapor pressure is required; such as for sealing ground joints on the backing side of oil diffusion pumps.

Description: Fluorescent probe. Long wavelength red labeling derivative for proteins. Can be used as a reversible inhibitor of the erythrocyte calcium pump as well as an effective phosphorescent probe in measurement of rotational diffusion of proteins and in fluorescence energy transfer (FRET) studies. EITC tagged molecules may be used together with fluorescein-5′-isothiocyanate (FITC) tagged molecules in fluoresce resonance energy transfer (FRET) based assays. Spectral properties: Abs/Em = 520/544 nm

Supplier: Adipogen
Description: N-Hexadecanoyl-L-homoserine lactone is a small diffusible signaling molecule and is a member of N-acyl-homoserine lactone family. N-acylhomoserine lactones (AHL) are involved in quorum sensing, controlling gene expression, and cellular metabolism. C16-HSL is a lipophilic, long acyl side-chain bearing AHL, produced by the LuxI AHL synthase homolog SinI involved in quorum-sensing signaling in S. meliloti, a nitrogen-fixing bacterial symbiont of certain legumes. C16-HSL is the most abundant AHL produced by the proteobacterium R. capsulatus and activates genetic exchange between R. capsulatus cells. It tends to localize in relatively lipophilic cellular environments of bacteria and cannot diffuse freely through the cell membrane. The long-chain N-acylhomoserine lactones may be exported from cells by efflux pumps or may be transported between communicating cells by extracellular outer membrane vesicles.
