Description

MA5-14665 can be used for immunofluorescent analysis of AFP in the endoderm derived from human embryonic stem cells. By Western blot, MA5-14665 detects endogenous AFP protein in the early hepatocyte-like cells derived from human embryonic stem cells. Product MA514665 is a smaller package size of MIA1301 (formerly sold as a Seradyn product).

Experimental details

Western blot analysis of alpha-fetoprotein was performed by loading 10 µg of whole cell extract from H9 ESCs, primary human hepatocytes, HepaRG cells, HepG2 cells, and H9 ESC-derived hepatocytes-like cells in reducing conditions and 10 µL Spectra Multicolor Broad Range Protein Ladder (Product # 26634) per well onto a Novex Bolt® 4-12% Bis-Tris Plus Gel with Bolt® MOPS running buffer and Bolt® Antioxidant. Proteins were transferred to a PVDF membrane using the iBlot 2 Dry Blotting System (Product # IB21001), and blocked with 5% non-fat milk in TBST for 1 hour at room temperature. alpha-Fetoprotein was detected at 67 kDa using an alpha-fetoprotein monoclonal antibody (Product # MA5-14665) at a concentration of 1 µg/mL in 5% non-fat milk in TBST overnight at 4°C on a rocking platform, followed by a goat anti-mouse secondary antibody (Product # A24518) at a dilution of 1:10,000 for 1 hour at room temperature. Chemiluminescent detection was performed using Pierce™ ECL Western Blotting Substrate (Product # 32106).

Experimental details

Western blot was performed using Anti-AFP Monoclonal Antibody (Product # MA5-14665) and a 68 kDa band corresponding to AFP was observed upon treatment with protein transport inhibitor in Hep G2 cells but not in MDA-MB-231 cells which are reported to be negative. Whole cell extracts (30 µg lysate) of Hep G2 (Lane 1), Hep G2 treated with 1X protein transport inhibitor (Product # 00-4980-03) for 4 hours (Lane 2), MDA-MB-231 (Lane 3) and MDA-MB-231 treated with 1X protein transport inhibitor for 4 hours (Product # 00-4980-03) (Lane 4) were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0322BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1µg/ml) and detected by chemiluminescence with Goat anti- Mouse IgG (H+L), Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005)..

Experimental details

Immunofluorescence analysis of alpha-fetoproprotein (AFP) (green) in the endoderm derived from human ES cells. Embryoid bodies (EBs) were generated from the H9 embryonic stem cell line (WiCell Research Institute, WA09) using Gibco® KnockOut™ Serum Replacement. After four days in suspension culture, EBs were plated on Geltrex™-coated tissue culture-treated polystyrene plates and continuously cultured for 21 days. EB cultures were then fixed and permeabilized according to the 3-Germ Layer Immunocytochemistry Kit (Product # A25538) and stained with anti-alpha-fetoprotein (Product # MA5-14665, 1:200 dilution, 5 uL/mL final) at 4°C overnight. Secondary staining was completed using Alexa Fluor™ 488-conjugated anti-mouse IgG (Product # A-11001) and DAPI (Product # D1306) for nuclear DNA (blue) for 1 h at room temperature. Stained wells were imaged at 40X using the EVOS® FL Auto Imaging System.

Experimental details

Immunofluorescence analysis of AFP was performed using 70% confluent log phase Hep G2 and MDA-MB-231 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with AFP Mouse Monoclonal Antibody (Product # MA5-14665) at 5 µg/mL in 0.1% BSA and incubated overnight at 4 degree and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, Alexa Fluor® 488 (Product # A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the composite image showing cytoplasmic and golgi staining of AFP in Hep G2. Panel e represents the merged image of MDA-MB-231 cells which do not have AFP expression. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60X magnification..
