Target: Glucagon (GCG)

Reactivity: Human

Host: Rabbit

Clonality: Polyclonal

Conjugate: This Glucagon antibody is un-conjugated

Application: ELISA, Western Blotting (WB), Immunohistochemistry (IHC), Immunofluorescence (IF), Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))

Specificity: This affinity purified antibody is directed against human Glucagon.

Cross-Reactivity (Details): A BLAST analysis was used to suggest cross-reactivity with the antigen based on 100% homology with the immunizing sequence to human, chimpanzee, and bonobo.

Purification: This product was affinity purified from monospecific antiserum by immunoaffinity purification.

Sterility: Sterile filtered

Immunogen: Glucagon antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an internal portion of human Glucagon.

Isotype: IgG

Application Details

Application Notes: Anti-Glucagon is tested in ELISA and Western Blotting. Although not tested, this antibody is suitable for immunohistochemistry. Expect a band approximately ~20.9 kDa corresponding to the appropriate cell lysate or extract. Specific conditions for reactivity should be optimized by the end user.

Full Methods

Primary Antibody: ABIN7448121

Secondary Antibody: anti-rabbit secondary antibody Alexa Fluor 488 (Thermo Fisher Scientific, A11034, lot # XJ357262)

Full Protocol:

• Perfuse mice with paraformaldehyde 4% in 0.1 M phosphate buffer pH 7.4 and post-fix of samples in the same fixative for an additional 2 h at RT.
• Wash, dehydrate, and embed samples in paraffin wax.
• Wash several times with 0.01 M PBS.
• Cut brain with a microtome into 6 µm sections and mount on glass slides.
• After paraffin removal processed sections for microwave antigen retrieval for 10 minutes (95-100° C) in 10 mM sodium citrate buffer (pH 6.0). After 20 minutes of spontaneous cooling, wash sections (distilled water, 2 times for 5 minutes each; followed by PBS for 5 minutes).
• Incubate sections for 1 h at RT in a humid chamber in PBS containing 1% ovalbumin (Sigma, A5378) and 0.3% Triton-X-100 (BioRad, 161-0407, lot 00583) to block non-specific binding sites.
• Incubate sections with primary rabbit anti- Glucagon (antibodies-online, ABIN7448121, lot 49549) diluted 1:50 and 1:100, in PBS-BSA-PLL ON at RT in a humid chamber.
• Wash sections 3x 5 min with 0.01 M PBS.
• Incubate sections with anti-rabbit secondary antibody Alexa Fluor 488 (Thermo Fisher Scientific, A11034, lot # XJ357262), 1:500, in 0.1M PBS, 1 hour at room temperature.
• Wash sections 3x 5 min in 0.01 M PBS.
• Mount specimens in Fluoroshield (Sigma, F6182, lot MKCB0153V).
• Acquire images Leica DM 6000B fluorescence microscope equipped with a digital camera at 40x magnification.

Background: Glucagon is a member of a multigene family that includes secretin. Glucagon is a 29-amino acid pancreatic hormone that counteracts the glucose-lowering action of insulin by stimulating glycogenolysis and gluconeogenesis. The human glucagon gene is approximately 9.4 kb long, contains 6 exons and 5 introns, and assigned to 2q36-2q37. This antibody is suitable for researchers interested in metabolic diseases, like diabetes, cell proliferation, differentiation, apoptosis, GCPR signaling, and calcium signaling research.
