Product Info
TCO-PEG4-DBCO is a heterobifunctional click chemistry reagent containing a TCO and a DBCO moiety. TCO group specifically and efficiently reacts with terrahydrazine at fast speed. DBCO is very reactive toward Azide through copper free click chemistry, the PEG spacer increases the aqueous solubility of the reagent. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Document
Product Info
Overview
Quantified standard to be used as a positive control or PCR quantification standard
Vigorously quantified using multiple methods
Includes partial sequence of STX-1 subunit A, and STX-2 subunit A genes (please refer to product insert for more details)
Compatible with E. coli O157:H7 TaqMan PCR Detection Kit and E. coli O157:H7 TaqMan PCR Detection Probe/Primer and Control Set
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).
Storage Conditions Upon receipt, store Norgen’s E. coli O157:H7 Quantified Bacterial DNA Standards at -20°C or lower. Avoid multiple freeze-thaw cycles. If needed, prepare smaller working aliquots and store at -20°C or lower.
Lateral Flow Assay designed for the detection of IgG antibodies against PF4/polyanion-complexes in human citrated plasma or Serum
This product is only available in Germany!
Method/Platform
lateral flow, immunoassay
Range/Assay Sensivity
Test Principle
IgG antibodies are resposible for the heparin induced thrombocytopenia.
Immobilized anti-human IgG on the membrane of the test unit binds patients IgG-antibodies which are previously captured by the PF4/polyanion-complex which is detected by intensely colored gold nanoparticles.
The presence of PF4/polyanion-complex becomes visible at a colored test line. The surplus of gold particles continues to migrate through the membrane and is captured at the control line by specific antibodies.
