Monoclonal Antibodies If titre is positive do one of the following 2 weeks later:
Cell Lines:
Maintenance of the cells:Stock solutions:
Seed macrophages at a density of 1.5x105 cells/ml in the medium described on next page. Add 2.5 ug/ml LPS which induces differentiation. Collect sup after 2-3 days, or when medium is getting too yellow. Induce 2 more times , each time with 1 ug/ml LPS and collect sup after 2 days each. Pool the sups, filter and use as recommended. (Could be aliquoted and stored at -20C.) Preparation of Media:for P3X63-Ag8.653: IMDM complete to 425 ml of IMDM add:
for fox-NY: IMDM or RPMI
for J774A.1: same medium as the one for the P3X63-Ag8.653 ( = Ag8 ). Growth conditions:
The Macrophages optimal density is 1.5x105/ml. When expanding them , use a "policeman" to scrape them; this is easier to do if they are growing in petri dishes at this stage. Freezing Hybridoma / Myeloma / macrophages.Freezing solution: 90% FCS + 10% DMSO, ice cold.
