* | * Put liposome solution, same as previous tries except with PEM instead of PEM-T on flow cell marked R | ||
* Take that cell out of the drawer at 9:13 am, rinse with PEM, seal with nail polish | |||
* Other flow cell, just rinse with PEM and then seal with nail polish | |||
* The first slide will be PLL without liposomes | |||
* Background with just PLL does not seem significant | |||
* There are bright spots, but they are not bleaching so they are probably just gunk | |||
* There is a very low level amount on the rhodamine filter, and slightly more brightness all over the flow cell on the FITC filter | |||
<br> | |||
* Now PLL with liposome mixture added | |||
* There is now basically nothing on the FITC filter - at least nothing I can see | |||
* On rhodamine there is bright red everywhere (uniform) in the flow cell | |||
<br> | |||
OK, so now that I am more comfortable with this process next steps are: | |||
<br> | |||
1) Make some more flow cells (rinsing after PLL bath)<br> | |||
2) Make some more liposomes - maybe with the mixtures I already made up in buffer, went through freeze/thaw, etc, and test with DLS<br> | |||
3) Try this again, this time with a more dilute mixture of liposomes, like crazy dilute, and see if it still has the uniform fluorescence<br> | |||
4) Fiddle around with that to see at about what concentration I still get uniform coverage<br> | |||
5) Now add MTs back in, try imaging with them again<br> | |||
