I am looking for a nice specific antibody anti-CD200r1 for its detection in mouse brain protein extracts. I am loading 20 micrograms of total protein in a 12% SDS-PAGE.
You could try rabbit polyclonal anti-CD200R1 antibody from Sigma-Aldrich or goat Anti-CD200R1 Antibody (Cat Number LS-C150164-100) from from LifeSpan BioSciences, both work well for WB
