Figure 1. ArciTect™ Human CRISPR Optimization Kit Exhibits High Editing Efficiency in hPSCs, T Cells, and CD34+ Hematopoietic Stem and Progenitor Cells (HSPCs)

Cells were electroporated with RNP complexes containing sgRNA targeting B2M complexed with ArciTect™ Cas9 Nuclease protein. The cells were cultured for 72 hours following electroporation and editing efficiency was monitored by flow cytometry to detect loss of B2M expression; n = 3 biological replicates (WLS-1C iPSCs/hPSCs) or n = 3 donors (T cells and CD34+ HSPCs). No EP: non-electroporated controls.

Figure 2. Anti-Human Beta-2-Microglobulin, Clone #35 Conjugates Exhibit Equivalent Performance Across Samples to Monitor B2M Knockout Efficiency Using the ArciTect™ Human CRISPR Optimization Kit

CD34+ HSPCs isolated from two independent donors were electroporated with RNP complexes containing sgRNA targeting B2M complexed with ArciTect™ Cas9 Nuclease protein. The cells were cultured for 96 hours following electroporation and editing efficiency was monitored by flow cytometry to detect loss of B2M expression using anti-human beta-2-microglobulin, clone #35, (A, B) APC-conjugated, (C, D) FITC-conjugated, and (E, F) PE-conjugated. The histograms were derived from gated events of viable (7-AAD-negative) cells. Orange histograms: RNP-electroporated samples; grey histograms: non-electroporated control samples.
