Recognizes the large N-terminal extracellular domain of Glutamate Receptor 2 (GluR2). No cross-reactivity observed with other AMPA/Kainate GluR subunits. On western blots of brain extracts from rat, macaque monkey, and dog, MAB397 recognizes a band at approximately 102 kDa corresponding to full length GluR2.
Other proteins noted by Western blot at 66 kDa or lower molecular weight appear to be breakdown products of GluR2 (Vissavajjhala, 1996). By immunohistochemistry GluR2 is widely distributed at both the cellular and synaptic levels. MAB397 recognizes GluR2 present in a vast majority of, but not all, GABAergic interneurons (Vissavajjhala, 1996).
Application
Immunocytochemistry: on 4% paraformaldehyde fixed cells was used in a previous lot:2-3 µg/mL (Vissavajjhala, 1996; Osten, 1998; Passafaro, 2001).
ELISA/RIA: A previous lot of this antibody was used in ELISA/RIA.(Vissavajjhala, 1996).
Western blot: 1-2 µg/mL (Vissavajjhala, 1996; Osten, 1998); membrane preparations are suggested for enhanced signals.
Optimal working dilutions and protocols must be determined by end user.
Anti-Glutamate Receptor 2 Antibody, extracellular, clone 6C4 detects level of Glutamate Receptor 2 & has been published & validated for use in ELISA, IC, IH, IP, RIA & WB with more than 50 product citations.
Quality
Routinely evaluated by Western Blot on mouse brain lysates.
Western Blot Analysis: 1:1000 dilution of this lot detected glutamate receptor 2 on 10 μg of mouse brain lysates.
