Paraformaldehyde (PFA) has been widely used as a cross-linking fixation agent.
It has been empirically recognized in a gold standard protocol that the PFA concentration for cell fixation, C _PFA, is 4%.

How are cells fixed with formaldehyde?

Formaldehyde is the most commonly used fixative; it works by chemically bonding adjacent macromolecules, such as proteins, together.
This process is known as crosslinking.
Most available formaldehyde preparations are actually paraformaldehyde (PFA, polymeric formaldehyde) dissolved in water or a buffer.

What percentage of formaldehyde does it take to fix cells?

Type of fixative: paraffin embedded tissues are most often fixed in either 10% (v/v) neutral buffered formalin (NBF) or fresh 4% (w/v) formaldehyde solution (“PFA”) made from paraformaldehyde power.

What is the process of formaldehyde fixation?

Formalin is saturated 37% formaldehyde solution dissolved in water.
It is important to note that a 10% formalin solution is equivalent to a 4% paraformaldehyde solution.
The sample is fixed in 1% formalin in (1X) PBS for 10 minutes at room temperature followed by three washes for 5 minutes each with (1X) PBS.

Methods

Cells are plated at an appropriate density and allowed to attach to the slide or dish (ex.
Fix the cells with 4% formaldehyde for 15 min at room temperature.
Gently wash the cells 3 times in PBS (5 min/wash) using a dropper to add PBS to the chamber followed by aspiration to remove the buffer.
