	ADRA2A-VLPs Protein, Human (HEK293, His) Alpha-2A adrenergic receptor; Alpha-2 adrenergic receptor subtype C10; Alpha-2A adrenoreceptor; Alpha-2A adrenoceptor; Alpha-2AAR	Human	HEK293
	ADRA2A-VLPs Protein, Human (HEK293, His) is recommended for animal immunization, ELISA. It is not recommended for receptor-ligand interaction detection and SPR/BLI assay since there are other irrelevant membrane proteins of the host on the VLP envelope, and the receptor-ligand interaction will have strong background interference. High requirements for chips and experimental protocols are needed for SPR/BLI assays. If VLP control is required, it is recommended HY-P701236. Tags can only be detected under denaturing conditions.
