Olaptesed pegol
Based on 1 Customer Validation
Olaptesed pegol (NOX-A12) is a L-oligoribonucleotide aptamer targeting CXCL12 based on a pegylated structure. Olaptesed pegol neutralizes CXCL12, and CXCL12 inhibition mobilizes chronic lymphocytic leukemia cells into the circulation and prevents their homing into the protective microenvironment. Olaptesed pegol can enhances the infiltration of human primary T cells and NK cells and inhibit tumor growth companied with anti-PD-1 antibody. Olaptesed pegol can be used for researches of colon cancer and lymphocytic leukemia.

Activité biologique
CXCL12[1]
Olaptesed pegol (10-100 nM, overnight incubation) dose-dependently enhances the infiltration of human primary T cells (CD8+, CD4+) and NK cells in heterotypic tumor-stroma spheroids (PSN-1/MS-5, HT-29/MS-5, H1299/MS-5, U251MG/MS-5) containing CXCL12, slightly promotes B cell infiltration, has no effect on monocyte infiltration, and results in low levels of Treg cell infiltration[2].
Olaptesed pegol (10 nM, combined with anti-PD-1 antibody, overnight incubation) synergizes with anti-PD-1 antibody to enhance the activation of Jurkat PD-1/luc T cells in the MS-5/CHO-PD-L1 spheroid model[2].
