N-(Boc-PEG4)-N-bis(PEG4-propargyl) is a trifunctional chemical containing two terminal alkynes and a Boc-protected primary amine. The terminal alkynes are used in copper click chemistry with azides to form stable triazole linkages with the target molecule while the carboxylic acids are reactive towards alcohols and primary amines to form esters and amides respectively.

Overview
Detection kits for the HPV (High and Low Risk)
Available in TaqMan format for analysis
More than 70 types of human papillomavirus (HPV) have been identified, and are generally classified as high-risk or low-risk depending on their relationship or lack of relationship with cancer and high-grade cervical intraepithelial neoplasia (CIN 2-3). HPV viruses are predominantly sexually transmitted and high-risk HPV types are a major risk factor for development of cervical cancer. Low-risk HPV types 6 and 11 have been associated with the presence of genital warts. There are many other low-risk HPV types that are not associated with genital warts or cervical cancer. Until now, HPV cannot be cultured in vitro, and immunological tests are inadequate to determine the presence of HPV cervical infection. On the other hand, biopsies can be analyzed by nucleic acid hybridization to directly detect the presence of HPV DNA. HPV 16 and HPV 18 have been considered as high-risk cancer associated HPV types. HPV types 31, 33, and 35 have been shown to have an intermediate relationship with cancer. Norgen’s Human Papillomavirus (HPV) (High and Low Risk) TaqMan PCR Detection Kits are suitable for the detection of HPV 33 and HPV 58.

Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
Short term stability: 2-8oC, Long term stability: See individual component labels
