Cluster of differentiation 2 (CD2) is a useful early T-cell lineage restricted antigen that is present in T-cell differentiation. As a pan-T-cell marker, CD2 staining is used for recognizing practically all normal T-cells, but may be deleted in some T-cell neoplasms. Since CD2 is present in most precursor and mature T-cell leukemias and lymphomas, it is useful in the evaluation of lymphoid malignancies. By using CD2 and CD25 staining, the recognition of systemic mastocytosis and mastocytic leukemia is supported.
These kits provide a convenient and rapid method to isolate total DNA from fresh, frozen and preserved stool samples, including those preserved using Norgen’s Stool Nucleic Acid Collection and Preservation Tubes (Cat. 45660). The universal protocol conveniently allows for the isolation of total genomic DNA from all the various microorganisms and host cells found in the stool sample simultaneously. Purifies the DNA with high yields and molecular weights of up to 50 kb plus. The purified DNA can be used with a number of downstream applications.
Stool DNA Isolation Kit (Spin Column)
Universal method to detect microorganism and host cell DNA simultaneously in stool samples. Eliminates PCR inhibitors including all traces of humic acid using a combination of chemical and physical homogenization and lysis. A simple and rapid spin column procedure is then used to further purify the DNA. The purified DNA is of the highest quality and is fully compatible with all downstream applications such as PCR, qPCR, NGS and microarrays since all humic acid substances and other PCR inhibitors are removed during the isolation process.
Stool DNA Isolation 96-Well Kit (High Throughput)
Fast and easy high throughput processing using centrifugation. Eliminates PCR inhibitors including all traces of humic acid using a combination of chemical and physical homogenization and lysis. A simple and rapid spin column procedure is then used to further purify the DNA. The purified DNA is of the highest quality and is fully compatible with all downstream applications such as PCR, qPCR, NGS and microarrays since all humic acid substances and other PCR inhibitors are removed during the isolation process.
Stool DNA Isolation Kit (Magnetic Bead System)
Fast and easy processing using a magnetic bead system. Robust lysis system (chemical lysis combined with a mechanical homogenization).
Stool DNA Isolation 96-Well Kit (High Throughput Magnetic Bead System)
This kit provides fast and easy processing using a magnetic bead system, and a robust lysis system (chemical lysis combined with a mechanical homogenization). High throughput and compatible with an automation robotic system.

E. coli O157:H7 is a rod-shaped, gram negative bacterium. It is an enterohemorrhagic strain of the common E. coli bacterium and infection by the O157:H7 strain is commonly associated with hemorrhagic colitis. E. coli O157:H7 is recognized by its somatic (cell wall) antigen (O157) and its flagella antigen (H7). In addition, E. coli O157:H7 is known to produce Shiga-like toxins, which cause severe symptoms. While most patients can recover from the infection, up to 15% of the patients may develop hemolytic uremic syndrome, a type of kidney failure that could be fatal. Infection of E. coli O157:H7 usually results from consumption of poorly prepared food including undercooked meat (particularly ground beef), untreated water or raw unpasteurized milk.
Norgen’s E. coli O157:H7 Quantified Bacterial DNA Standards are cloned fragments of the two Shiga-like toxin regions purified using Norgen’s sample preparation technology. They include partial sequences of STX-1 subunit A gene and STX-2 subunit A gene. Please refer to Appendix A for sequence information. The purified DNA is quantified vigorously using multiple methods including spectrophotometry, gel densitometry and real-time PCR. It is intended to be used as positive controls or PCR quantification standards for E. coli O157:H7. This product is compatible with Norgen Biotek’s E. coli O157:H7 Taqman PCR Detection Kit (Cat. TM41350) and E. coli O157:H7 Taqman PCR Detection Probe/Primer and Control Set (Cat. TM41310).
