NeuroMab™ Anti-CXCR4 BBB Shuttle Antibody(NRZP-1022-ZP3799)

Figure 1 shows the competition of specific [ 125 I]SDF1 binding to 414H5 and 515H7 Mabs on the cell membrane of CHO-K1 cells stably expressing wild-type human CXCR4 (T total binding; NS non-specific binding).

Figure 2 shows the modulation of G protein activation by 414H5 Mab by monitoring the [35S]GTPγS binding response of wild-type CXCR4 receptors stably expressed in NIH-3T3 cells.

Figure 3 shows the modulation of G protein activation by anti-CXCR4 monoclonal antibodies 414H5 and 515H7 by monitoring the [35S]GTPyS binding response of HeLa human tumor cells stimulated with SDF-1 (10 and 100 nM).

Figure 4 shows that SDF-1 and 414H5 Mabs modulate the binding of CXCR4 receptor to different interaction partners by bioluminescence resonance energy transfer (BRET) method in HEK293 cells.

Figure 5 shows the inhibition of forskolin-stimulated cAMP production by SDF-1 and 414H5 and 515H7 Mabs in NIH3T3 cells stably expressing the CXCR4 receptor.

Figure 6 shows the modulation of G protein activation by anti-CXCR4 monoclonal antibodies 414H5 and 515H7 by monitoring the [35S]GTPγS binding response of a constitutively active mutant Asn119Ser CXCR4 receptor stably expressed in CHO-K1 cells.

Figure 7 shows that CXCR4 Mab 414H5 inhibits SDF-1-induced migration of U937 cells in vitro.

Figure 8 shows the inhibition of MDA-MB-231 xenograft tumor growth by anti-CXCR4 Mab 414H5 in Nod/Scid mice.

Figure 9 shows the competition of murine m414H5 and m515H7 mAbs and chimeric mAbs c414H5 and c515H7 for specific [125I]SDF1 binding to the cell membrane of CHO-K1 cells stably expressing wild-type human CXCR4 (T total binding; NS non-specific binding).

Figure 10 shows the modulation of G protein activation by murine m414H5 and m515H7 mAbs and chimeric mAbs c414H5 and c515H7, as monitored in NIH-3T3 cells stimulated with SDF-1 (10 nM) [35S]GTPγS binding response of stably expressed wild-type CXCR4 receptor).

Figure 11 shows the effects of anti-CXCR4 murine m414H5 and m515H7 mAbs and chimeric mAbs c414H5 and c515H7 on G protein activation by monitoring the [35S]GTPγS binding response at HeLa human tumor cells stimulated with SDF-1 (10 nM). adjust.

Figure 12 shows the inhibition of SDF-1-induced migration of U937 cells by CXCR4 Mabs m414H5 and c414H5 in vitro.

Figure 13 shows the activity of anti-CXCR4 chimeric Mabs c414H5 and c515H7 in the U937 Nod/Scid mouse survival model.
