Confocal Analysis of Apical and Basal ICAM-1 Expression Following Polarized Cytokine Delivery










Introduction: At the last meeting, I introduced the new stirred cell device acquired in Tom’s lab (here). I have expanded the study to observe changes in flux and concentration for each of the membranes used. Experiments: Each of the experiments was run with BSA having an initial concentration of 1mg/mL, this concentration is determined using spectrophotometry…
I spent some more time in understanding the numbers I am getting for our device simulations. In my simulations, I am assigning a conductivity value for my cell layer. Technically, from this information and by knowing the thickness and area of the cell layer, I can analytically calculate the value of resistance that the cell…
Today I looked at 3 more wafers: w158 (9/7/07) – some pinholes, overwhelming amount of very fine debris, not cbs as far as I can tellw160 (9/7/07) – some pinholes, debris, no cbsw171 (9/26/07) – many pinholes, lots of debris, no cbs w158 (200x) – small particles Link to updated report.

Chris and I got to play on the new Zeiss scanning transmission electron microscope (STEM) today (learn about STEM here). We didn’t get to spend a lot of time on it, but here are some quick images we snapped. wafer 416 @ 25kx (left) and 65kx (right) Even though we’re imaging in transmission mode, the…
Motivation We have discussed the optimization of our in situ permeability assay at length. This assay relies on confocal microscopy, which may not be accessible to all users of the µSiM. Therefore, we developed an alternative permeability assay in the µSiM that is an endpoint, sampling assay. The protocol for this assay can be found…
