Norgen’s FFPE RNA Purification Kits provide a rapid method for the isolation and purification of total RNA (including microRNA) from formalin-fixed paraffin-embedded (FFPE) tissue samples in as little as 1 hour. Using formalin to fix tissues leads to crosslinking of the RNA and proteins, and the process of embedding the tissue samples can also lead to fragmentation of the RNA over time. Norgen’s FFPE RNA Purification Kits provide conditions that allow for the partial reversing of the formalin modifications, resulting in a high quality and yield of RNA. These kits are able to purify all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA), depending on the age of the FFPE tissue as fragmentation of the RNA is known to occur over time. The RNA is preferentially purified from other cellular components without the use of phenol or chloroform.
FFPE RNA Purification Kit (Spin Column)
Maximum loading volume of 650 μL per column, and a maximum binding capacity of 50 μg per column.
FFPE RNA Purification 96-Well Kit (High Throughput)

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.

Character
High flatness sample shelf:
Silicone oil thermal conductive shelf, high-precision processing method of upper and lower clamping, shelf temperature uniformity can reach ±0.5°c
Integrated cavity:
Integrated chamber, the shelf and cold trap are located in the same chamber, the steam conduction is faster and the freeze-drying effect is better
Refrigerating and heating control system:
Using thermally conductive silicone oil with a high temperature range and precise PID control algorithm, the control accuracy can reach ±0.5°C. Sample shelf temperature range: -70°C~ +80°C
Freeze-drying endpoint testing system:
The pressure comparison method is used to determine the freeze-drying end point. The freeze-drying end point test can be automatically performed after the analytical drying stage to ensure that the moisture content of the material reaches the standard requirements.
