Synonyms

CD3E & CD3D, CD3 delta & CD3 epsilon

Source

Alexa Fluor 488-Labeled Human CD3E&CD3D Heterodimer Protein, His Tag&Tag Free (CDD-HA2W5) is produced via conjugation of AF488 to Human CD3E&CD3D Heterodimer Protein, His Tag&Tag Free with a new generation site-specific technology under Star Staining labeling platform. Human CD3E&CD3D Heterodimer Protein, His Tag&Tag Free is expressed from human 293 cells (HEK293). It contains AA Asp 23 - Asp 126 (CD3E) & Phe 22 - Ala 105 (CD3D) (Accession # P07766-1 (CD3E) & P04234-1 (CD3D)).

Predicted N-terminus: Asp 23 & Phe 22
