LR White Resin树脂包埋剂
Sections from LR White appear “bumpy“ in contrast to Epon resin sections. It is possible that Epon links covalently to tissue proteins while LR White links more weakly.

LR White Resin

18181	LR White Resin, Medium, 500ml	each

I -MSDS-

Resin with initiator （BPO） packaged separay. Accelerator 18185 can be used for cold-cure （room temperature）. Heat cure is 24 hours between 50°C and 65°C. Gelatin capsules are recommended for temperatures below 60°C. Tightly closed BEEM® Capsules and PTFE Molds with ACLAR™ as cover （Cat. 10506 or 10508） work well at 65°C. Widely used because of excellent immunolabeling results. LR White is a polar, monomer polyhydroxylated aromatic acrylic resin （seePTFE Molds）.

Sections from LR White appear "bumpy" in contrast to Epon resin sections. It is possible that Epon links covalently to tissue proteins while LR White links more weakly. "LR White appears to act in a manner similar to ice in a freeze-fractured specimen."17 A. Yamamoto and Y. Tashiro, using AFM, found a strong relief surface on LR White sections, 3-4nm on average. Depressions ranged from 6 to 30nm. Protrusions could be seen on the complimentary surface. Epon sections show relatively smooth surfaces.18 Micrographs appear similar to freeze-etched images but scaled to nm instead of µm. Viscosity ~= 8cP
