Scientific Data Images for Human FABP5/E-FABP Antibody

Detection of Human FABP5/E‑FABP by Western Blot.

Western blot shows lysates of human heart tissue, human brain (cerebellum) tissue, and human placenta tissue. PVDF membrane was probed with 1 µg/mL of Rat Anti-Human FABP5/E-FABP Monoclonal Antibody (Catalog # MAB3077) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for FABP5/ E-FABP at approximately 15 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

FABP5 in HUVEC Human Cells.

FABP5 was detected in immersion fixed HUVEC human umbilical vein endothelial cells using Rat Anti-Human FABP5 Monoclonal Antibody (Catalog # MAB3077) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the Northern-Lights™ 557-con-jugated Anti-Rat IgG Secondary Antibody (yellow; Catalog # NL013) and counter-stained with DAPI (blue).

Western Blot Shows Human FABP5/E‑FABP Specificity by Using Knockout Cell Line.

Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and FABP5/E-FABP knockout HeLa cell line (KO). PVDF membrane was probed with 1 µg/mL of Rat Anti-Human FABP5/E-FABP Monoclonal Antibody (Catalog # MAB3077) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for FABP5/E-FABP at approximately 15 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockout HeLa cell line. GAPDH (Catalog # MAB5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: FABP5/E-FABP

FABP5, also known as epidermal fatty acid binding protein (E-FABP), is expressed in skin, lens, adipose tissue, endothelial cells, heart, brain and placenta. FABP-5 is associated with keratinocytes and adipocytes, and is suggested to promote fatty acid availability to enzymes, protect cell structures from fatty acid attack, and target fatty acids to nuclear transcription factors. Human FABP-5 shares 80%, 81%, and 92% aa identity with mouse, rat and bovine FABP-5, respectively.
