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”

4 put MEOH into tray “MEOH” 5 put 50 ul of 3% PFA in two columns ( use a autoclavable 5 – 50 ul ) 6 wait 15 sec. , than aspirate off the liquid 7 wash 2 x with 0.01% BSA/PBS ( use the manifold I for “in”) 8 put 75 ul MEOH in each column 9 repeat steps 5-9 10 when finish with entire plate , wait 5 minutes Staining for BrDU and Myosin


11 aspirate off the MEOH of plate 12 add 75 ul 2N HCL to each well ( use the autoclavable 50-300 ul) 13 wait 12 minutes 14 aspirate off the HCL 15 wash 4x with TBS –Tween ( use the vacum pette –7.5 ml ) 16 mix 8 ul Mouse anti BrDU (BU) antibody + 3.5 mls TBS +10% GS in tray “BSA” , the concentration is 1:500 17 aspirate off the TBS -Tween 18 put 30 ul into each well , wrap plate in parafilm and put at 4 C overnight 19 wash 4x with TBS-Tween ( 2x then wait 2 min. ,then wash 1x, then wait 3 min. , then wash) 20 mix 35 ul DAKO Rhodamine rabbit anti mouse + 3.5 mls TBS-Tween +10% GS in tray “BSA” concentration is 1:100 21 aspirate off the TBS-Tween 22 put 30 ul into each well 23 wait 20 minutes 24 rinse 4x with TBS-Tween 25 mix 35 ul Rhodamine from swine anti rabbit + 3.5 mls TBS+10% GS in tray”BSA” ( wash tray when finished) 26 aspirate off the TBS-Tween 27 put 30 ul into each well from Rhodamine ( swine anti rabbit) 28 wait 20 minutes 29 wash 4x with TBS- Tween 30 aspirate off the liquid 31 mix 8 ul of Mouse anti Myosin antibody+ 3.5 mlsTBS-+10% GS in tray”BSA”, the concentration is1:500 32 wait 2 hours 33 wash 4x with TBS-Tween 34 mix 35 ul of FITC rabbit anti mouse+ 3.5 mls TBS-Tween+10%GS in tray “BSA” , the concentration is 1:100 35 wait 30 minutes 36 wash 4x with TBS-Tween 37 mix 35 ul of FITC swine anti rabbit + 3.5 mls TBS-Tween+10%GS in tray “BSA” , the concentration is 1:100 38 wait 30 minutes 39 wash 4x with TBS-Tween 40 mix 3.5 ml TBS-Tween + 7 ul Hoechst 41 aspirate off the liquid 42 put 30 ul into ach well 43 wait 5 minutes 44 wash 3x with TBS-Tween 45 aspirate off the liquid 46 add 75 ul MEOH per well 47 wrap plate with parafilm and store at 4 C
