Általános leírás

PARAFILM stretches up to 200% and clings even around irregular shapes and surfaces. The sealing film is free of plasticizers and consists primarily of polyolefins and paraffin waxes. PARAFILM M is resistant up to 48 hours against many polar substances, eg saline solutions, inorganic acids and alkaline solutions.

Protect the integrity of research applications with a tight moisture-barrier that holds a strong seal and doesn′t release from glassware, despite off-gassing
Reduce the risk of tampered data with a covering that is odorless, colorless and semi-transparent
Prevents moisture and volume loss due to material composition and tight seal
Flexible and self-sealing material allows it to cling around irregular shapes and surfaces
Stretches more than 200% of original length
Resistant up to 48 hours against many polar substances such as saline solutions, inorganic acids and alkaline solutions

Recent developments in optical tissue clearing have been difficult to apply for the morphometric analysis of organs with high cellular content and small functional structures, such as the kidney. Here, we establish combinations of genetic and immuno-labelling for single cell

PloS one, 4(9), e6909-e6909 (2009-09-10)
The peripheral circadian clock in mice is entrained not only by light-dark cycles but also by daily restricted feeding schedules. Behavioral and cell culture experiments suggest an increase in glucose level as a factor in such feeding-induced entrainment. For application
