ATCC Lactobacillus delbrueckii; subsp. lactis; Strain L110
Lactobacillus delbrueckii subsp. lactis strain L110 was isolated from dairy products. This bacterial type strain is propagated aerobically in lactobacilli MRS medium.
Biochain Institute Inc Frozen Tissue Section - Dementia: Brain: Parietal Lobe, 5 slides/PK
BioChain's tissue products are based on the sample repository network established following the IRB-approved ethical standard and procedures. BioChain's Frozen Tissue Slides are ideal for rapidly identifying cellular localization of RNA or protein. A single human adult normal tissue with 5-10 um thickness is mounted on a positively charged glass slide. The slides are fixed and dehydrated with acetone for consistent results with in situ hybridization and immunohistochemistry. More organs may be available upon request.
ATCC Pfizer Pneumoccal polysaccharide powder Type 70 (d33F) 2mg
Purified pneumococcal polysaccharide type 33F is manufactured by Pfizer, Inc. for small quantity distribution by ATCC. The pneumococcal polysaccharide type 33F can be used to assay for type-specific antibodies, research immune responses, and study immunodeficiencies.
Eurofins Discoverx ChemiScreen NPBW1 Neuropeptide B/W Receptor Membrane Preparation, 1 vial. (HTS180M)
The ChemiScreen NPBW1 Neuropeptide B/W Receptor Membrane Preparation is derived from proprietary stable recombinant cells to ensure high levels of NPBWR1 surface expression. ChemiScreen membrane preps can be used to screen for ligand binding affinities using a competitive radio-labeled ligand approach. Increased binding affinities will lead to higher radioactive signal. Membrane preps contain 1 mL of 1 mg/mL frozen membranes derived from a stably modified clonal cell line which was chosen for optimal receptor expression.

ATCC pRS424 phagemid; in E. coli
This is a YE-type shuttle vector encoding the beta-galactosidase alpha peptide, permitting blue-white visual detection. It contains promoters for in vitro RNA synthesis and priming sites useful for sequencing. It also contains the REP3 and FRT sequences necessary for high copy propagation in yeast. In S. cerevisiae, the number is about 20 per haploid cell. In the range of 1.5 +/? 1.7% of progeny per doubling. The order of the major features in this plasmid is: ori(fi) ? lacZ ? T7 promoter ? MCS (KpnI-SacI) ? T3 promoter ? lacI - ori (pMB1) ? ampR ? ori(2 micron) ? TRP1.
