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)
• wait 12 minutes
• aspirate off the HCL
• wash 4x with TBS –Tween ( use the vacum pette –7.5 ml )
• 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)
