3,4-Dibromo-Mal-PEG4-amide-DBCO is a PEG linker containing a dibromomaleimide group and a terminal DBCO group. The dibromomaleimide group allows for two points of attachement because both of the bromine atoms can be substituted. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. PEG linkers are hydrophilic moieties, therefore the attachment of a PEG linker to a compound increases it’s water solubility properties in aqueous media. Reagent grade, for research purpose.

For the simultaneous detection of up to four targets in one reaction. Save time, cost, and consumables while maximising data generation.
About
ProbeSure Multiplex Master Mix is an enhanced version of ProbeSure Master Mix, formulated to enable users to analyse up to four targets in one reaction well. For example, two bi-allelic SNPs or one reference gene and a further three genes of interest.
Users will require a plate reader capable of reading FAM, HEX, ATTO 550, ATTO 647N and ATTO 633 (the wavelengths of each of these can be found in our ProbeSure Multiplex Master Mix User Guide). ProbeSure Multiplex Master Mix is supplied at 2x concentration for convenience and is supplied with the ATTO 633 normalising dye at either high level (500 nM final concentration), low level (25 nM final concentration) or without ATTO 633.

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.
