Invitrogen™ eBioscience™ Intracellular Fixation and Permeabilization Buffer Set 

Designed for use in intracellular staining and flow cytometric analysis and has been specially formulated to reduce non-specific staining of fluorochrome-labelled antibodies and increase fluorescence signal-to-noise ratios.

Manufacturer:  Invitrogen™ 88882400

Catalog No. 50-112-9037

Includes: IC Fixation Buffer
Permeabilization Buffer (10X)

Description

• In the first step, live cells can be 'fixed' with the Fixation Buffer, which cross- links proteins
• The second step, using the Permeabilization Buffer, creates holes in the membrane and allows the intracellular staining antibodies to enter the cell effectively
• Subsequent washing steps, antibody additions, and incubations after cell permeabilization should be performed using the Permeabilization Buffer
• Final washing step and cell resuspension prior to running the sample is done using Flow Cytometry Staining Buffer (cat. 00-4222).
• This kit is commonly used to stain cytoplasmic proteins and proteins in the secretory pathway such as chemokines and cytokines
• Not recommended for intranuclear staining. Instead, please refer to the Foxp3/Transcription Factor Buffer Set for nuclear staining
• Before the fixation step, it is recommended to label the live cells using one of the Fixable Viability Dyes and then proceed with fixation
