Used primarily in electron microscopy, LR White acrylic resins provide excellent tissue preservation and antigen retention, making them ideal for immunolabeling studies. They are hydrophilic and maintain good penetration of antibodies, which enhances detection efficiency. Commonly used for embedding biological samples, especially when preserving epitopes for post-embedding immunogold labeling. Also applied in plant and animal tissue research, as well as in materials science for embedding soft materials prior to ultrathin sectioning. The resin cures at low temperatures, allowing use with heat-sensitive samples.
