Anti-Potassium Channel, Voltage-Gated Kv3.1 pS503 Antibody is suitable for use in Western Blotting and IHC. Expect a band of approximately 100kDa in size corresponding to Kv3.1 voltage-gated potassium channel protein phosphorylated at Ser503 in the appropriate cell lysate or extract. Specific conditions for reactivity should be optimized by the end user.
