Q:

What antibodies can be used against the GFP produced by pmaxGFP™ and pmaxFP™-Green vectors? What antibodies can be used to detect denatured GFP? What antibodies can be used to detect the RFP expressed by pmaxFP-Red?

A:

Most of the commercial antibodies for GFP do not detect GFP expressed from pmaxGFP or pmaxFP-Green vectors. The origin of the protein expressed by the pmaxGFP control plasmid and pmaxFP-Green is from the green fluorescent protein CopGFP, cloned from copepoda Pontellina plumata (Arthropoda; Crustacea; Maxillopoda; Copepoda). Most commercial antibodies for GFP are designed to react with proteins isolated from other organisms. For example, Clontech`s GFP is from Aequorea victoria (jellyfish), and would not react with antibodies to pmaxGFP or pmaxFP-Green.

Evrogen offers antibodies against the copepod GFP which can be used to detect the GFP expressed by our vectors:

Cat. No. AB513 will recognize denatured protein expressed from both pmaxGFP.
