Experimental details: Western blot analysis of FABP4 using 30 µg of 293T lysate. Samples were loaded onto a 15% SDS-PAGE gel and probed with a FABP4 polyclonal antibody (Product # PA5-30591) at a dilution of 1:1000.

Experimental details: Knockdown of Fatty acid-binding protein, adipocyte was achieved by transfecting 3T3-L1 cells with Fatty acid-binding protein, adipocyte specific siRNAs (Silencer® select Product # s62398, s62400) and then the cells were differentiated to adipocytes. Western blot analysis (Fig. a) was performed using Whole cell extracts from the Fatty acid-binding protein, adipocyte knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blot was probed with FABP4 Polyclonal Antibody (Product # PA5-30591, 1:2,000 dilution ) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:20,000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to Fatty acid-binding protein, adipocyte. A non-specific band was observed at 30 kDa.

Experimental details: Western Blot using FABP4 Polyclonal Antibody (Product # PA5-30591). Various whole cell extracts (30 µg) were separated by 15% SDS-PAGE, and the membrane was blotted with FABP4 Polyclonal Antibody (Product # PA5-30591) diluted at 1:500. The HRP-conjugated anti-rabbit IgG antibody was used to detect the primary antibody.

Experimental details: Western blot was performed using Anti-FABP4 Polyclonal Antibody (Product # PA5-30591) and a 15 kDa band corresponding to Fatty acid-binding protein, adipocyte was observed across cell lines. Whole cell extracts (40 µg lysate) of 3T3-L1 (Lane 1), 3T3-L1 differentiated to adipocytes (Lane 2) were electrophoresed using NuPAGE™ 12% Bis-Tris Protein Gel (Product # NP0341BOX). 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 (1:2,000 dilution) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036,1:20,000 dilution using the iBright™ FL1500 Imaging System (Product # A44115). Chemiluminescent detection was performed using SuperSignal™ West Dura Extended Duration Substrate (Product # 34076). Upon differentiation of 3T3-L1 cells to adipocytes the expression of FABP4 should upregulate as observed along with a non specific band at ~ 30 kDa.

Experimental details: Figure 4 TDP-43 and TDP-35 levels do not correlate with tau phosphorylated at Thr181 . (A) Representative microphotographs of 3xTg-AD brain sections depicting hippocampal CA1 pyramidal neurons stained with the anti-tau antibody AT270, which recognize tau phosphorylated at Thr181 (n = 6/age group). (B) Representative Western blots of proteins extracted from 6- and 12-month old 3xTg-AD mice probed with the AT270 antibody. beta-actin is used as a loading control. (C) Quantitative analysis of the blots shows that the steady-state levels of AT270 were significantly higher in the brains of 12-month-old 3xTg-AD mice compared to 6-month-old mice (n = 6/age group; p < 0.05). Data are presented as +- SEM and analyzed by t-test analysis. (D-E) Linear regression analysis indicated that the levels of AT270 in the brains of 6-month-old 3xTg-AD mice did not correlate with the levels of TDP-43 (r 2 = 0.09148, p = 0.56) and TDP-35 (r 2 = 0.1491, p = 0.45). (F-G) Similarly, no correlation between AT270 and TDP-43 (r 2 = 0.4644, p = 0.14) and TDP-35 (r 2 = 0.4469, p = 0.15) levels was observed at 12 months of age.
