Abstract
Time-lapse into immunofluorescence (TL into IF) imaging combines the wealth of information acquired during live-cell imaging with ease of access for static immunofluorescence markers. In the field of mechanobiology, connecting live and static imaging to visualize cell biology dynamics is often troublesome. For instance, nuclear blebs are deformations of the nucleus that often rupture spontaneously, leading to changes in the molecular composition of the nucleus and the nuclear bleb. Current techniques to connect cellular dynamics and their downstream effects via live-cell imaging, followed by immunofluorescence, often require third-party analysis programs or stage position measurements to accurately track cells. This protocol simplifies the connection between live and static imaging by utilizing a gridded imaging dish. In our protocol, cells are plated on a dish with an engraved coordinate plane. Individual cells are then matched from when the time-lapse ends to the immunofluorescence images simply by their known coordinate location. Overall, TL into IF offers a straightforward method for connecting dynamic live-cell with static immunofluorescence imaging, in an easy and accessible tool for cell biologists.
Key features
• This protocol directly links live-cell imaging to immunofluorescence imaging.

Overview of time-lapse into immunofluorescence imaging using a gridded dish
Background
Both time-lapse and immunofluorescence imaging are essential to understanding cell biology dynamics and their effects. However, by performing live cell and static experiments independently of one another, information is lost. Particularly in the field of mechanobiology, it has been difficult to connect nuclear shape fluctuations and ruptures to their causes and consequences due to the disconnect between these two types of experiments. We recently overcame this barrier through the development of TL into IF [1,2]. For instance, it is known that abnormal nuclear morphology is associated with numerous human diseases, including cancer [3]. Nuclear blebs are a type of nuclear deformation that is prone to spontaneous rupture and known to cause cellular dysfunctions, including DNA damage [4–9]. However, how nuclear blebs form and their molecular composition before and after rupture has yet to be fully elucidated. It was recently noted that decreased DNA density is the best indicator of a nuclear bleb, and that loss of lamin B1 in the bleb indicates previous nuclear rupture [1,2,10,11]. Enrichment or loss of other proteins in the bleb, such as lamin A/C, emerin, and cGAS, has also demonstrated an association with nuclear rupture [1,12,13]. These experiments, as well as numerous cell biology experiments, require a direct connection between dynamic live-cell and immunofluorescence imaging to understand cellular dynamics and their downstream effects. Current methods of tracking live-cell imaging into immunofluorescence imaging often require third-party applications such as MATLAB or matching microscope stage position coordinates [14,15]. The primary advantage of our method is the elimination of these extra steps; while the use of third-party applications allows for automated tracking, our protocol does not require any external applications. Additionally, matching stage position coordinates may prove difficult if different microscopes are used for live-cell and immunofluorescence experiments. The only special equipment needed for our protocol is a gridded imaging dish (D35-14-1.5GI, Cellvis), which has a coordinate plane engraved on the glass coverslip that is visible in transmitted light. By seeding cells on the gridded dish, cells are simply matched from time-lapse imaging to immunofluorescence imaging via their location on the coordinate plane. Gridded coverslips have been used in the past for similar imaging techniques [16,17]. Our protocol decreases the complexity of the experiment by confining it to a single imaging dish, which in turn increases its accessibility and utility for cell biology.
