HCM196 Yeast Extract Peptone Dextrose Agar

Overview

Optically clear adhesive film with pressure activated adhesive. Seal is peelable; suitable for qPCR and other imaging techniques including crystallization.

• Optically clear seal specifically developed for optical applications, particularly qPCR
• It is non sticky when removed from the packaging; this aids handling when wearing gloves
• The adhesive is contained within small capsules, allowing light to pass through to ensure the optical clarity of the seal
• When the seal is in position, pressure can be applied to burst the capsules, releasing a strong adhesive only where the seal touches the raised well rims of the plate – the rest of the seal area above the wells remains optically clear
• For all adhesive seals, the best sealing results are achieved using our Hand Roller or KAPS 500 Auto Sealer

Description

Saxitoxins (STXs) are naturally occurring alkaloids produced by some marine dinoflagellates and by strains of various species of freshwater cyanobacteria.  Saxitoxin is one of the prevalent paralytic shellfish toxins (PSTs). It belongs to a family of potent neurotoxins with a molecular weight around 300 Da. Saxitoxin and its derivatives are alkaloids composed of a tetrahydropurine ring system with a highly polar guanidinium group. Due to their significant toxicity, saxitoxins are closely monitored in marine environments where they can accumulate during harmful algal blooms (HABs).  In 2009 an action level of 0.6ppb (600ppt) was recommended by EFSA as a guidance framework have been established to manage saxitoxin levels in water.
