Electron Microscopy Sciences Stain-'N'-Temp Slide

This device is used as an aid when programming a microwave oven to achieve an ideal target temperature of 20-100ul staining volumes. The tool is designed to give quantitative temperature information about the droplet during staining of tissue sections on electron microscope grids.

This unit is a 4-well "PTFE" coated glass slide, each well 8 mm in diameter which will maintain the uniform shape of the droplet; 4 liquid crystal temperature strips ranging from 35 to 50 degree are affixed to each well to monitor the microwave oven temperature.

Developed in collaboration with Dr. Gary Login, Beth Israel Hospital, Boston, MA

ATCC pBAD24 in E. coli

pBAD24 phagemid in Escherichia coli DH5 alpha One of several tightly controlled expression vectors (ATCC 87393-87402) regulated by the arabinose operon. Vectors differ in replicon, antibiotic resistance marker, multiple cloning site and need for translation initiation sequences. Cultures should be grown in minimal media for more reproducible induction of expression. Expression is induced in glycerol-containing media by addition of arabinose. Expression is repressed by addition of glucose or other catabolites. Vector contains an optimized Shine-Dalgarno ribosome binding site, translation initiation codon and Kozak sequence (relevant for expression in eukaryotic cells) which promote a high level of expression of cloned inserts. The following primers can be used for sequencing of cloned inserts: 5' primer (27 - 45 bp upstream of the NheI site) 5' - CTGTTTCTCCATACCCGTT-3';

AdipoGen Grams Safranin Solution

Chemical. CAS 477-73-6. Formula C20H19ClN4. MW 350.84. Synthetic. Gram Safranin Solution is a reagent recommended for use in qualitative procedures to differentiate gram-negative from gram-positive organisms. The Gram staining allows a fast differentiation of bacteria in Gram-positive and Gram-negative. The mureine structure of the bacteria walls is the basis of the color affinity. Bacteria will be stained with Grams crystal violet solution - an aniline dye - in the first step. After the treatment with iod solution, a dye-iod complex will form. During the decolorizing step, this complex stays in the multilayer mureine structures of the Gram-positive bacteria and they will appear blue. Gram-negative bacteria have a monolayer mureine structure only, the dye-iod complex does not stay bound to the cellwall, they will be decolorized. Gram-negative bacteria will be counterstained by safranin solution and appear orange.
