Analysis of GFAP in differentiated human Neural Stem Cells (NSC). NSC derived from H9 cells (WiCell, Madison, WI) were differentiated in NSC differentiation medium [containing N2 and B-27 supplements (Life Technologies), recombinant human BDNF and GDNF (Peprotech), dibutryl cyclic AMP (Sigma)] for 11 days followed by AGM™ Astrocyte Growth Medium (Lonza) for 16 days. The cells were fixed (BD Cytofix™ buffer, Cat. No. 554655) for 20 minutes at room temperature, permeabilized with BD™ Phosflow Perm/Wash Buffer I (Cat. No.557885), and then stained with PE Mouse anti-GFAP (left panel) and co-stained with APC mouse anti-CD44 (Cat. No. 559942) as shown in the right panel. This antibody conjugate also works with BD ™ Phosflow Perm Buffer III. Flow cytometry was performed on a BD LSR™ II flow cytometer.
Analysis of GFAP in Neural Stem cells (NSC). NSC were isolated by sorting from Embryoid bodies and were grown for 8 passages post sort, fixed (BD Cytofix™ buffer, Cat. No. 554655) for 20 minutes at room temperature, permeabilized with BD™ Phosflow Perm Buffer I (Cat. No.557885), and then stained with either PE Mouse anti-GFAP (solid line) or PE Mouse IgG2b, κ Isotype Control (Cat. No. 555058, dashed line).

Preparation And Storage
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- An isotype control should be used at the same concentration as the antibody of interest.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.

Antibody Details
1B4
GFAP (Glial Fibrillary Acidic Protein) is the major protein of glial filaments in differentiated astrocytes. BD Biosciences offers a panel of monoclonal antibodies (4A11, 1B4, 2E1) that specifically recognize GFAP. They do not cross-react with other intermediate filaments such as vimentin, neurofilament proteins, desmin, keratin, neurotubules or microfilaments.

Format Details
PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
