DBCO-C5-acid is an analog of DBCO-Acid with an extended 5-carbon atom spacer arm. The extended 6-carbon atom spacer arm improves its derivatization efficiency and the stability of the yielded conjugates. This spacer arm also improves solubility in organic solvents such as dichloromethane, chloroform, THF, and ethyl acetate. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research use only.

Used for the selective isolation and culture of Listeria monocytogenes.
Columbia Blood Agar Base provide carbon and nitrogen sources, vitamins and growth factors，maintains balanced osmotic pressure; Listeria hydrolyzes aesculin and reacts with iron ions to form black 6,7-dihydroxycoumarin; lithium chloride and other antibiotics can inhibit Gram-negative bacteria and most Gram-positive bacteria; agar is the coagulant of the culture medium.

Weigh 55.5 g of this product, add 1000 mL of distilled water or deionized water, stir, heat and boil until completely dissolved, divide into Erlenmeyer bottles, sterilize at 121℃ for 15 min. Cool to about 50℃, add 1 bottle of SR0500 supporting reagent A and 1 bottle of B per 100 mL, mix well and set aside.
The following quality control strains were inoculated and cultured at 35-37℃ for 24h. The results are as follows:
| Quality control strains | Growth |
| Listeria monocytogenes ATCC19115 | Gray-green colonies with a black depression in the center and black surrounding |
| Enterococcus faecalis ATCC29212 | – |
| Escherichia coli ATCC25922 | – |

Synovial fluid is secreted into the joint cavity from the inner membrane of synovial joints. Synovial fluid is a plasma ultrafiltrate which contains proteins derived from both the blood plasma and produced by cells within the joint tissues. It lubricates the articulating joints as well as supplies oxygen and nutrients while removing carbon dioxide and metabolic wastes from the chondrocytes in the surrounding cartilage. Septic arthritis is usually caused by bacterial, viral or fungal infections to the synovial fluid. Staphylococcus aureus is the most common bacterial infection causing Septic arthritis. Diagnosing Septic arthritis is done through joint fluid (synovial fluid) analysis, blood tests or imaging tests.
Norgen’s Synovial Fluid Bacterial Genomic DNA Isolation Kit provides a fast, reliable and simple procedure for isolating the highest quality and the highest quantity of bacterial genomic DNA from various amounts of synovial fluid ranging from 1 mL up to 10 mL. Purification is based on using Norgen’s proprietary resin separation matrix. The kit is designed to isolate all Gram +ve and Gram -ve strains. Moreover, the kit allows the user to elute the purified bacterial genomic DNA into a flexible elution volume ranging from 25 µL to 50 µL. The purified bacterial gDNA is eluted in an Elution Buffer that is compatible with all downstream applications including PCR, qPCR, methylation-sensitive PCR, Southern Blot analysis and NGS.

Hepatitis C virus infection is a major cause of chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma (HCC) worldwide. Neither a vaccine nor an effective treatment is available for HCV. Pegylated interferon-α (PEG-IFN- α), combined with ribavirin, is the current standard therapy. Its efficiency ranges between 20-80%, depending on the HCV genotype. Unfortunately, many HCV infected patients do not respond to or do not tolerate the IFN-based therapy. Therefore, the number of patients progressing to HCC, as a result of HCV infection, is expected to increase over the next 20-30 years. The natural history of the disease reveals the elusive nature of the virus in a number of features. First, the infection is often detected incidentally at the time of blood donation as the acute infection is clinically asymptomatic in most patients. Second, HCV successfully escapes multi-specific host immune responses in the majority of patients which establishes persistent infection. Third, a significant number of persistently infected individuals remain unaware of the infection for decades, until liver fibrosis, cirrhosis and/or hepatocellular carcinoma develop.
