Description

GCG Antibody

Images & Validation

• Tested Applications: ELISA, IF, IHC, WB
• Dilution Range: ELISA: 1:24,800-1:44,800, IHC: 1:100, IF: 5-15µg/mL

  Anti-Glucagon is tested in ELISA, IF, IHC-P, and Western Blot. 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

Key Properties

• Antibody Type: Primary Antibody
• Host: Rabbit
• Clonality: Polyclonal
• 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.
• Target: GCG
• Purity: This affinity purified antibody is directed against human Glucagon. This product was affinity purified from monospecific antiserum by immunoaffinity purification. 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.
• Conjugation: Unconjugated

ELISA Results of Rabbit Anti-Glucagon Antibody. Each well was coated with 1 µg of conjugate. The starting concentration of antibody in the dilution series was 5 µg/ml. The titer is 1:34800 Glucagon - Free peptide [Green Line], 1:47200 Glucagon Standard - BSA conjugated [Blue Line], and 1:20500 Glucagon - BSA conjugated [Purple Line]. Each point on the Y-axis represents a 3-fold dilution. 3% Fish Gel (p/n orb348587), HRP conjugated Goat anti-Rabbit IgG (H&L) (p/n orb347673), and TMB substrate were used for detection.
