How do you store fixed cells?
in ice-cold acetone and then store them in the -80°C in aluminium foil.
You can store them there for several years if needed.
It gives very nice IF staining.
Lately, i used cell cultures fixed in acetone and stored for 12 months in the -80°C and the stainings were very pretty using golgi staining, ER staining etc..
How do you store unstained slides?
It is recommended that unstained slides be kept at −80°C and individually wrapped in aluminum foil, irrespective of whether the slides are dipped in paraffin, if the IHC staining will not be performed in the same week that the slides are cut.
How long can paraffin be stored?
Not to worry – our experience (Firefly Pure Paraffin Lamp Oil) is that the shelf life of paraffin lamp oil will last indefinitely if stored in a sealed container.
How long do fixed cells last?
How long will my cells last once fixed? You’ll be pleased to hear that cells fixed in ethanol are stable at 4oC or –20oC for months.
Are fixed cells dead?
The basics of fixation and permeabilization But, fixed and permeabilized cells are dead, and you lose the ability to look at dynamic biological processes.
How long can fixed cells be stored in PBS?
about 6 monthsPopular Answers (1) Care that PBS is always on you fixed cells. Evaporation could dammage your cells. I put Parafilm all around the plates to prevent from drying. I keep them about 6 months in PBS before immuno.
How do you store a cytospin slide?
Fix the air-dried slides for 10 min in acetone at room temperature (alternatives fixatives include 10 min in 2% paraformaldehyde or 10 min in 100% methanol). The fixation method should be optimized for each experiment. Let the slides dry for 2h, wrap in foil or put into sealed boxes and store at -20°C until use.
How do you store Cryosections?
I cut thin sections (14 um) of fixed frozen brain and spinal cord tissues and mount on Superfrost Plus slides. While I’m sliding them, I let them dry for 10-15 mins at RT and then I store in -80C in a slide box. I wrap the slide box in aluminum foil.
What is a cytospin used for?
A cytocentrifuge, sometimes referred to as a cytospin, is a specialized centrifuge used to concentrate cells in fluid specimens onto a microscope slide so that they can be stained and examined.
How do you store paraffin slides?
Most paraffin blocks can be stored at 20-27°C. Paraffin blocks must not be exposed to temperatures that exceed 27°C (80°F). 7.2 Labeled paraffin blocks should be placed in plastic zip-lock bags with the LDMS barcode label on the outside of the bag.
How do you store paraffin embedded tissue?
You can store paraffin blocks at room temperature in a box for years. But before you start sectioning again put them into the fridge for a couple of hours. This makes sectioning easier. Paraffin section which are not mounted on glas slides could also stored in flat boxes at room teperature over years.
