Biotin-PEG12-DBCO is a biotinylating reagent comprised of DBCO, a click chemistry handle that is frequently used to conjugate with azides on target molecules, and biotin, which is useful for affinity-based applications such as pull-down assays or for ligating with streptavidin proteins. The PEG12 imparts the hydrophilicity of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Cryptosporidium is a parasite found in water that causes an infection in mammals termed cryptosporidiosis. It is one of the most common water-borne diseases and is found world-wide. It affects the intestines of mammals and typically causes an acute short-term infection. The most common symptom is self-limiting diarrhea in healthy individuals, however in immunocompromised individuals the symptoms are particularly severe and often fatal. There is no specific treatment for cryptosporidiosis other than fluid rehydration and management of any pain. Therefore early detection of Cryptosporidium in water is the foremost action to prevent the infection.

Storage Conditions and Product Stability All kit components can be stored for 1 year after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
CDX-2 is a caudal-related homeobox transcription factor that is expressed by intestinal epithelial cells. CDX-2 is a useful marker for gastrointestinal carcinoma, and for determining the origin of gastrointestinal metastatic adenocarcinoma and carcinoids. Anti-CDX-2 is used for differentiating lung and metastatic colorectal adenocarcinoma, however mucinous ovarian carcinoma also react positively with Anti-CDX-2, thereby limiting the ability to differentiate from metastatic colorectal adenocarcinoma.

Overview
Quantified standard to be used as a positive control or PCR quantification standard
Vigorously quantified using multiple methods
Listeria monocytogenes has emerged as a significant foodborne pathogen that poses a serious public health problem. As the causative agent of Listeriosis, L. monocytogenes has the highest rate of fatality among all foodborne pathogens. L. monocytogenes is a facultatively intracellular, Gram-positive bacterium. Due to its ability to survive high and low temperatures as well as low pH, it could resist various food processing technologies, as well as grow at food storage temperatures. L. monocytogenes is known to be associated with raw meat, unpasteurized milk and dairy products, vegetables, and seafood. As little as 1000 organisms may cause the disease with pregnant, new-born, and immunocompromised individuals being the most susceptible.
Norgen’s Listeria monocytogenes Quantified Bacterial DNA Standard is prepared from cultured bacteria using Norgen’s sample preparation technology. The purified DNA is quantified vigorously using multiple methods including spectrophotometry, gel densitometry and real-time PCR. It is intended to be used as a positive control or PCR quantification standard for Listeria monocytogenes.
Upon receipt, store Norgen’s Listeria monocytogenes Quantified Bacterial DNA Standard at -20oC or lower. Avoid multiple freeze-thaw cycle. If needed, prepare smaller working aliquots and store at -20oC or lower.
