Description

Not all cyanobacterial strains produce toxins. However, the toxin-producing strains cannot be distinguished from the nontoxin-producing strains by traditional light microscopy, commonlyused to monitor water bodies.  An alternative for the differentiation of potentially toxic strains from nontoxic strains is to use molecular methods to detect the presence of toxin biosynthetic genes. Such methods are already available and could be used for the detection and identification of potential microcystin and nodularin producers present in environmental samples (Attogene catalog number NA2024).

Screening for the toxin itself, can be very costly.  In turn, real time PCR for the detection of a gene region responsible for assembling  in cyanobacterial strains and environmental samples can be a key indicator for the prescense of cyanobacteria capable of expressing the aetokthonotoxin toxin.  Attogen has thus, designed primer pairs and probes targeting a the conserved gene region in order to enable the amplification and detection of several producer genera using real time PCR.  Screening for the toxin genes can save significant costs and act as a triage for samples needing to be analyzed for the toxin itself.

Cyanobacterial neurotoxin aetokthonotoxin (AETX), a peculiar pentabrominated biindole alkaloid implicated in fatal Vacuolar Myelinopathy.  This neurodegenerative disease was first recorded in 1994 during an outbreak of bald-eagle poisonings at De Gray Lake in Arkansas, USA.  AETX was experimentally confirmed to be produced by the true branching heterocytous cyanobacterium Aetokthonos hydrillicola.  The production of AETX is dependent on bromide (Br−) availability, and likely linked to its hyper-accumulation by the host plan.  Thus regular monitoring of A. hydrillicola (accompanied by assessment of Br− and AETX levels) is highly advisable to predict the possible threat of further VM outbreaks.

The cyanobacterial AetA gene which encodes the unique FAD-dependent halogenase involved in the pathway for AETX synthesis has been adapted to develop a -aetokthonotoxin specific quantitative PCR (qPCR) assay.

Overview

• Detection kits for the HPV (High 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.
