I am at work and just wanting to check I am not being an idiot, does anyone know any specifics about agarose?

Yes.

It's a variation on part of the Agadoo dance.

I think that it replaces the "push pineapples shake the tree" section.

I havent done anything so you can come out from under your desks, I was just wanting to knwo if there was a specific spec for this CAS number but its ok I have found it out now.

Agarose is how a dyslexic writes a well know catalogue shop

I vaguely remember its a gelatinous substance derived from seaweed. Historically and in a modern context, it is chiefly used as an ingredient in desserts throughout Japan, but in the past century has found extensive use as a solid substrate to contain culture medium for microbiological work. The gelling agent is an unbranched polysaccharide obtained from the cell walls of some species of red algae, primarily from the genera Gelidium and Gracilaria, or seaweed (Sphaerococcus euchema). Commercially it is derived primarily from Gelidium amansii.

Agar (agar agar) can be used as a laxative, a vegetarian gelatin substitute, a thickener for soups, in jellies, ice cream and Japanese desserts such as anmitsu, as a clarifying agent in brewing, and for paper sizing fabrics. Chemically, agar is a polymer made up of subunits of the sugar galactose. Agar polysaccharides serve as the primary structural support for the algae's cell walls,

The word "agar" comes from the Malay word agar-agar (meaning jelly). It is also known as kanten, China grass, or Japanese isinglass. The various species of alga or seaweed from which agar is derived are sometimes called Ceylon moss. Gracilaria lichenoides specifically is referred to as agal-agal or Ceylon agar.[1]

In Malay and Indonesian, it is known as agar-agar. In Japanese, it is known as kanten (寒天) meaning "cold weather," referring to the fact that it is harvested in the winter months. In Mandarin Chinese as hǎicài (海菜) meaning "ocean vegetable". In Taiwanese Minnan it is known as chhài-iàn (菜燕) meaning "vegetable swiftlet," i.e., similar in texture to the nest of the edible-nest swiftlet used in bird's nest soup. In Korea, it is known as hancheon (한천). In China, it is known as hǎizàoqióngzhī (海藻瓊脂) or dòngfěn (凍粉). In the Philippines, it is known as gulaman in Tagalog, Apayao, Bikol, and Pangasinan, guraman in Ilokano and gurguraman in Sambali.[2] In Thai it is known as wóon (วุ้น).

Agarose molecules have molecular weights of about 120,000. The gel network of agarose contains double helices formed from left-handed threefold helices. These double helices are stabilized by the presence of water molecules bound inside the double helical cavity [508]. Exterior hydroxyl groups allow aggregation of up to 10,000 of these helices to form suprafibers

Thats how I remember it but I could be wrong. bbolt
