I would recommend a free antibody database available at labome.com.

In particular, BioLegend has mouse monoclonal (122) anti-HVEM ab for WB. Also, R and D Systems offers mouse monoclonal (94801) ab for WB. Besides, eBioscience has mouse monoclonal (eBioHVEM-122) ab suitable for WB. In addition, Santa Cruz has both mouse monoclonal (D-5) and goat polyclonal (N-19) abs for WB. Also, OriGene, Abcam, US Biological and Abnova have either mouse monoclonal or goat polyclonal abs for WB.
