S2 Media 15x100mm Chameleon™ COLOREX™ Orientation and Tryptic Soy Agar with 5% Sheep Blood (Orient|BAP), Biplates, 10/pack
Chameleon™ COLOREX™ Orientation and Tryptic Soy Agar with 5% Sheep Blood (Orient|BAP) Biplates: TSA w/ 5% Sheep Blood (Blood Agar) is a non-selective, differential growth medium utilized for the isolation and cultivation of non-fastidious and fastidious organisms. Hemolytic response can be utilized to differentiate microorganisms. TSA w/ 5% Sheep Blood is not the medium of choice for anaerobes. Chameleon™ COLOREX™ Orientation is a non-selective, differential, chromogenic culture medium used for the qualitative direct detection and presumptive identification of uropathogens associated with urinary tract infections (UTI). • Product complies with BAM, CLSI, and USDA reference methods and performance criteria.• Media should be used by trained professionals within a laboratory setting.• For in vitro diagnostic (IVD) use.• Product is not intended for use in the diagnosis or treatment of disease or other human conditions.
LICOR Chameleon Vue Pre-stained Protein Ladder (250 L)
The Chameleon Vue Pre-stained Protein Ladder offers multi-colored, pre-stained proteins for molecular weight estimation. This pre-stained protein ladder allows easy visualization of gel migration and protein size, provides a vibrant color scheme that allows you to quickly orient your gel or membrane, can be used for chemiluminescent detection when paired with the WesternSure Pen, and is optimized for use with Bis-Tris and Tris-Glycine gels.

Sigma Aldrich Fine Chemicals Biosciences VivaspinR 500 50 kDa MWCO
Designed for fast nondenaturing concentration of biological samples by membrane ultrafiltration. Up to 30-fold concentration of the sample can be achieved with recovery of the target molecule typically exceeding 95%.Vivaspin(R) sample concentrators are designed for fast nondenaturing concentration of biological samples by membrane ultrafiltration. Up to 30-fold concentration of the sample can be achieved with recovery of the target molecule typically exceeding 95%. The entire process is performed in a single tube with an upper compartment containing sample and lower compartment separated by a semipermeable membrane with a molecular weight cut-off (MWCO) selected by the user. Centrifugation is applied to force solvent through the membrane leaving a more concentrated sample in the upper chamber.Vivaspin(R) sample concentrators cater for sample volumes from 100 mul to 20 ml with a range of molecular weight cutoff values from Mr 3 000 to 100 000. for maximum recovery select a MWCO at
FUJIFILM Biosciences WIDE-VIEW TM Prestained Protein Size Marker Ⅲ, 500uL
A stained protein size marker. There are twelve recombinant proteins contained, and they covalently bind to blue,red and green chromophores. A band for 75 kDa shows red, 25 kDa shows green and other bands exhibit blue color. This item should be kept at -20 Degrees Celcius.
