Mouse anti Guinea Pig CD90 antibody, clone CT4 recognizes guinea pig THY-1 (CD90), a small but heavily glycosylated member of the immunoglobulin superfamily. Clone CT4 was originally identified as recognizing a guinea pig homing receptor (Kraal et al. 1986) and later confirmed as recognizing the guinea pig homologue of human and rodent CD90 (Schäfer et al. 1999) by purification and microsequencing. Guinea Pig CD90 is notable for its level of N-linked glycosylation, rendering it an apparent molecular mass of ~36 kDa, higher than that seen in most other species where CD90 has been identified and characterized.

Guinea pig CD90 (according to Uniprot entry Q9WUR5) demonstrates 82% amino acid identity with human CD90, 74% with murine CD90 and 76% with rat.

Guinea pig CD90 is highly expressed in the brain and unlike other species is also expressed on most resting B lymphocytes (Schäfer et al. 1999)

Mouse anti Guinea Pig CD90 antibody, clone CT4 has been used extensively for the flow cytometric analysis of guinea pig cell populations (Gupta et al. 2012).
