Sulfo DBCO-PEG4-Maleimide is a water-soluble click chemistry reagent with a maleimide group and a DBCO moiety. The hydrophilic PEG spacer arm improves solubility in aqueous buffers. Maleimide group specifically and efficiently reacts with thiols to form stable thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description

Not all cyanobacterial strains produce toxins. However, the toxin-producing strains cannot be distinguished from the nontoxin-producing strains by traditional light microscopy, commonly
used 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 the anaC gene in cyanobacterial strains and environmental samples can be a key indicator for the prescense of cyanobacteria capable of expressing the Anatoxin toxin.  Attogen has thus, designed primer pairs and probes targeting a the conserved anaC 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.

Overview

• Detection kits for Streptococcus dysgalactiae
• Available in TaqMan format for analysis

Mastitis is the single most costly disease of dairy cattle resulting in the reduction of milk yield and quality. The inflammation of the utter is mainly caused by infection of various bacteria. Streptococcus dysgalactiae, a Lancefield group C α-hemolytic gram-positive bacteria, is a common pathogen in subclinical and clinical mastitis causing substantial economic losses in dairy herds. Streptococcus dysgalactiae has been isolated from infected mammary glands and teat injuries and is transmitted primarily during milking. However, detection of S. dysgalactiae in other cow tissues such as tonsils, mouth and vagina, and occurrence of S. dysgalactiae mastitis during the non-lactating period in herds, suggests that the organism also behaves as an environmental pathogen.

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.
