Although it is a convenient technique to use liquid culture in plant research for generating bulk tissue, liquid culture makes it impossible to the study of root hair development and root system architecture. Plant tissues need to span in three-dimensional space for growth and differentiation. MP Bio offers a variety of gelling agents to allow researcher to optimize the plant tissue culture conditions for each species. Agar, produced from seaweed, is the most common type of gelling agent to solidify media for plant tissue culture, and it is ideal for routine applications. We also offer gellan gum powder and alginic acid sodium salt.
