Herein, we present a protocol that details the technical aspects and essential requirements to ensure robust IG gene sequence analysis in patients with chronic lymphocytic leukemia (CLL), based on the accumulated experience of the European Research initiative on CLL (ERIC).

¹Experimental Immunology Unit, Division of Immunology, Transplantation and Infectious Diseases, IRCCS San Raffaele Scientific Institute, ²Vita-Salute San Raffaele University

We describe a rapid and robust protocol to enrich invariant natural killer T (iNKT) cells from mouse spleen and expand them in vitro to suitable numbers for in vitro and in vivo studies.

¹Gynecological Surgery and Endometriosis Departmental Unit, San Raffaele Scientific Institute

In this protocol, CO₂fiber laser technique is demonstrated for the surgical treatment of ovarian endometriosis, which represents a viable alternative in terms of fertility preservation with the major advantage of not being dependent on the surgeon's skills and personal experience.

Here, we present a protocol for the in vitro selection of engineered transcriptional repressors (ETRs) with high, long-term, stable, on-target silencing efficiency and low genome-wide, off-target activity. This workflow allows for reducing an initial, complex repertoire of candidate ETRs to a short list, suitable for further evaluation in therapeutically relevant settings.
