HOPE ® Fixation System A2d
BioSciences
Achieve multiple applications including immunohistochemistry without
antigen unmasking on paraffin embedded tissue. HOPE ® =Hepes-glutamic
acid buffer mediated Organic solvent Protection Effect. HOPE ®
is a combination of amino acids and glucose blended together with
an organic buffer. Dehydration by acetone as the single dehydrating
agent and pure paraffin denature proteins and preserve nucleic acids
and antigenic-structures allowing clearly visible molecular level results.
HOPE ® is a two part system, both are required for required for application.
Cold Pack Required.

Grids for TEM
High quality specimen grids known for their beam stability and useful for supporting thin specimen
sections. Samples for transmission electron microscopy must be “supported” on thin transparent
film grids to hold the specimen in place while in the lens of the TEM. Manufactured with a “shiny”
side for easy identification. The general range of grids are available in copper, nickel and gold. Grids
vary in thickness from 7 mils (178 m) to 5 mils (12.7 m) depending on mesh size, the highest mesh
size having the thinnest grids. All grids are 3.05mm in diameter.
