PreparationofLowDensity,CollagenaseDigestedSplenocytes
1. Dilute 2 ml of 4000 U/ml Collagenase D as follows: 1 ml into 9 ml HBSS/Ca++/Mg++ (=400U/ml) and 1 ml into 39 ml HBSS/Ca++/Mg++ (=100U/ml). Put on ice.2. Place 5 ml of the 100U/ml solution in a 10 cm dish. Over a dry dish, inject spleens with 100U/ml solution. Hold spleen with forceps and push onto 22-G needle while slowly injecting 1 ml collagenase solution. Tear open the spleen with the needle and transfer to dis......阅读全文
