CPA1 (clone MSVA-601M) is a new marker for immunohistochemistry with very high sensitivity and specificity (>99%) for acinar cell carcinoma of the pancreas. A study on 15,680 tumors of >100 different tumor entities was recently published in the American Journal of Surgical Pathology.[1]

Acinar cell carcinoma of the pancreas makes up for only 1-2% of pancreatic tumors but is misdiagnosed in a considerable fraction of cases. Based on the data by Uhlig et al, the use of MSVA-601M results in a considerably safer distinction of this tumor entity.

The immunohistochemical visualization of CTLA-4 on formalin fixed tissues has so far been hindered by a relative lack of CTLA-4 antibodies suitable for immunohistochemistry.

In a recent study published in Laboratory Investigation by nature, researchers from the University of Hamburg have successfully analyzed 4582 tumor samples from 90 different tumor entities for quantification of CTLA-4 positive lymphocytes in formalin fixed archival tissues[2]

In their paper, Dum et al. utilized two antibodies including our newly developed clone MSVA-152R in combination with artificial intelligence to reliably count CTLA-4 positive cells. Based on these data, the antibody MSVA-152R has emerged as a highly useful tool for research on CTLA-4.
