Anti fgfr 1 antibody

Sunitinib and sorafenib were from LC Laboratories (Woburn, MA, USA). Sodium bicarbonate and HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) were from Sigma-Aldrich. Recombinant human VEGF was from Peprotech (#100-20-10). Cycloheximide was purchased from Santa Cruz biotechnology (#SC-3508). For Western blot analysis, the following primary antibodies and concentrations were used: anti-phospho-Akt antibody (1:500) (#4060; Cell Signaling Technology), anti-Akt antibody (1:1000) (#2920; Cell Signaling Technology), anti-VEGFR-2 antibody (1:1000) (#2479; Cell Signaling Technology), anti-VEGFR-1 (1:500) (#sc-316; Santa Cruz biotechnology), anti-β-actin antibody (1:5000) (#A2228; Sigma Aldrich), anti-Tie-2 antibody (1:500) (#MAB313; R&D systems) and anti-FGFR-1 antibody (1:1000) (#sc-121; Santa Cruz Biotechnology). Immunohistochemical staining were performed with anti-CD31 antibody (#Rb-10333-PO; Thermo Scientific). For immunofluorescence anti-CD31 (1:50) (# 553370; BD Pharmigen) and anti-VEGFR-2 antibody (1:50) (#2479; Cell Signaling Technology) were used. For flow cytometry, the following antibodies and dilutions were used: anti-CD31 (1:100) (#17-0319; eBioscience), anti-avb3 integrin (1:100) (MAB1976; Millipore), anti-VCAM-1(1:100) (#12-1069; eBioscience), anti-ICAM-1 (1:100) (#12-0549; eBioscience) and anti-MCP-1 (1:100) (#12-7099; eBioscience).

Whole-cell lysates (30 μg) were separated using SDS-PAGE and immunoblotted with specific antibodies. Anti-phospho-FGFR1 antibody was purchased from Abcam, anti-FGFR1 antibody (Santa Cruz Biotechnology). The other antibodies have been described previously [18 (link)].
