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.

Product Info
endo-BCN-PEG8-acid is a BCN-containing crosslinker reagent. The terminal carboxylic acid is reactive with primary amine groups in the presence of activators (e.g. EDC, or HATU). The BCN group enable copper free click chemistry with azide -tagged biomolecules. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Detection kits for Chlamydia/Neisseria gonorrhoeae
Available in TaqMan format for analysis
Chlamydia trachomatis, the causative agent of Chlamydia, is a Gram negative bacteria. Transmission of the bacteria occurs via contact with infected bodily fluids which then infect mucosal membranes. It can be transmitted from mother to child during pregnancy and infect the eyes causing conjunctivitis. The genital infection causes urethritis, epididymitis and prostatitis in males and Pelvic Inflammatory Disease (PID) in females with an increased risk of contracting HIV. The infection can be treated with a course of antibiotics. Sexually transmitted infections in females are most often asymptomatic, but can be noticeable in chronic pain of the pelvic region, vaginal bleeding and painful urination. Infection of the ovaries, fallopian tubes or uterus causes Pelvic Inflammatory Disease (PID) which can lead to difficulties in conceiving, increased risk of ectopic pregnancy or infertility. Infections in males are more likely to be symptomatic, causing painful urination, discharge from the penis and swollen testicles and may eventually cause infertility if left untreated.
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 transmitted by sexual contact and usually causes infection in cells of the mucous membrane of the male urethra or the endocervix and urethra in females. During infection, polysaccharides are released from the bacteria that stimulate host cell production of tumour necrosis factors that cause an inflammatory response. There is no vaccine against N. gonorrhoeae infection and antibiotic resistance is beginning to increase, therefore treatment includes a course of antibiotics that will be effective against resistant strains. Complications in males caused by the infection can result in prostatitis or orchitis if the bacteria spread. In females, invasion of the fallopian tubes or ovaries can result in salpingitis or ovaritis respectively, with any of these infections possibly resulting in sterility.

The D-Glucose Assay Kit (Megaplex Red) provides a simple robust method for the measurement of D-glucose. This kit utilises a highly sensitive Megaplex Red probe which when coupled to horseradish peroxidase (HRP) and glucose oxidase (GOX) enzymatic reactions, allows for the measurement of D-glucose in a sample. Upon oxidation of the probe by HRP, a coloured product (resorufin) is formed that can be measured in fluorescence mode using excitation between 530-560 nm and emission at ~ 590 nm* or colourimetrically at 570 nm.
*The excitation and emission maxima of Megaplex Red are 570 nm and 585 nm respectively.
Fluorometric/UV method for the determination of D-glucose content in a variety of samples.
Advantages
