BrdU and myosin staining
Fixing Cells:
- thaw 6% PFA in 37 C waterbath , place on ice
- put 5 ml PBS + 5 ml 6% PFA in tray “PFA” , mix well
- put 0.01% BSA/PBS into tray “BSA”
- put MEOH into tray “MEOH”
- put 50 ul of 3% PFA in two columns ( use a autoclavable 5 – 50 ul )
- wait 15 sec. , than aspirate off the liquid
- wash 2 x with 0.01% BSA/PBS ( use the manifold I for “in”)
- put 75 ul MEOH in each column
- repeat steps 5-9
- when finish with entire plate , wait 5 minutes
Staining for BrDU and Myosin:
- aspirate off the MEOH of plate
- add 75 ul 2N HCL to each well ( use the autoclavable 50-300 ul)

- mix 8 ul Mouse anti BrDU (BU) antibody + 3.5 mls TBS +10% GS in tray “BSA” , the concentration is 1:500
- aspirate off the TBS -Tween
- put 30 ul into each well , wrap plate in parafilm and put at 4 C overnight
- wash 4x with TBS-Tween ( 2x then wait 2 min. ,then wash 1x, then wait 3 min. , then wash)
- mix 35 ul DAKO Rhodamine rabbit anti mouse + 3.5 mls TBS-Tween +10% GS in tray “BSA” concentration is 1:100
- aspirate off the TBS-Tween
- put 30 ul into each well
- wait 20 minutes
- rinse 4x with TBS-Tween
- mix 35 ul Rhodamine from swine anti rabbit + 3.5 mls TBS+10% GS in tray”BSA” ( wash tray when finished)
- aspirate off the TBS-Tween
- put 30 ul into each well from Rhodamine ( swine anti rabbit)
- wait 20 minutes
