Neisseria gonorrhoeae is a Gram-negative coccus of the Neisseria genus. N. gonorrhoeae is usually seen in pairs infecting human cells. It has a circular DNA genome of approximately 1Mbp encoding over 2000 genes. N. gonorrhoeae is the etiological agent of the sexually transmitted infection (STI) gonorrhoea, which globally causes an estimated 60 million new cases of gonococcal disease annually. It is second only to Chlamydia trachomatis as the most reported notifiable sexually transmitted disease. Infections with N. gonorrhoeae are primarily restricted to the mucus membranes of the endocervix, urethra, rectum, and pharynx. In females, gonorrhoea is a major cause of pelvic inflammatory disease and may lead to tubal infertility, ectopic pregnancy, and chronic pelvic pain, whereas in males it primarily causes urethritis. Importantly, these infections may often be asymptomatic, thereby contributing to further transmission and maintenance of the disease within populations.
Norgen’s Neisseria gonorrhoeae Quantified Bacterial DNA Standard is prepared from pelleted bacteria grown on culture plates 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 Neisseria gonorrhoeae.

DBCO-STP Ester is an amine-reactive, water-soluble labeling reagent, including a DBCO group for click reactions with azide groups on target molecules and an STP ester group, which can react with primary amines, forming covalent amide bonds. STP esters typically display much better stability toward hydrolysis in aqueous media, resulting in more efficiency and better reproducible labeling of biopolymers. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
