agarose
This term refers specifically to the purified polymer used in laboratory settings, distinguishing it from the broader category of agar. It is characterized by its ability to form a porous, semi-solid matrix that acts as a molecular sieve, allowing scientists to sort nucleic acids by size.
As a chemical substance and material, it is treated as an uncountable mass noun. It does not have a plural form in standard scientific usage; instead, quantities are specified by weight or concentration, such as grams of agarose or a percentage of agarose in a buffer solution.
