Sigma-Aldrich A2576-25G Agarose, Ultra-Low Gelling Temperature, 25G

Agarose is a polymer extracted from agar or agar-bearing marine algae. This purified linear galactan hydrocolloid comprises alternating co-polymers D-galactose and 3,6-anhydro-L-galactose units connected by α-(1→3) and β-(1→4) glycosidic bonds. Agarose is highly biocompatible and possesses variable mechanical and diffusion properties. Agarose can be used as a gelling agent, to separate nucleic acids electrophoretically.

Application

• Agarose has been used:
• in thaumatin and elastase protein crystallization
• in microcasting using a polydimethylsiloxane (PDMS) mold with micro-channel
• in agarose micro-confinement array
• Yields unusually strong gels for an ultra-low gelling agarose. Ideal for electrophoresis of heat-labile samples and for growth of hybridomas or other cell lines.
