VA-hospital sorting on Alex-FISH E.coli (EtOH-fixed) - 30min-hybridization samples[edit]
Background[edit]
- The new FISH-labeled E.coli was performed with only 30min hybridization (Made on 06-07-'10)
- For this sorting, I pre-run a 1000cell sorting to cover full plate before the real sample sorting
Procedure[edit]
- Add 900uL 1XPBS into the sample (100uL) in the amber tube.
- Material need for sorting:
- 8-well PCR tube stirps (on 96-well rack). Filled up 3uL 1X PBS in PCR tubes. UV-treatment for 15min.
- UV clean sealing film (Bio-rad)
- UV clean zip bag for transporting sample + rack

Discussion[edit]
- The 30min hybridization showed similar results as 90min hybridization protocol.
- There still have two peaks showing when the sorting number is increased.
- The background is very low in this result compared to the previous results (03-30-'10). I am not sure if the short-hybridization helps to reduce the negative-labeling.
