It is possible to obtain 10 ml of ascites fluid or more from a mouse by regular tapping. The ascites fluid can be collected from an anaesthetized mouse.
The rate of growth of the resulting ascites tumour is in general very variable and can be from less than two or more than five weeks. Sino Biological can offer serum-free hybridoma production serivce by the use of serum-free medium.įor producing monoclonal antibodies in vivo, mice are primed by intraperitoneal injection with 10 5 - 10 7 hybridoma cells.
Culture in vitro provides a more pure preparation of antibody. Typical culture supernatants yield up to l00μg/ml of antibody, the exact amount depending upon the cell density and rate of growth. The cell density is maintained between 10 5 and 10 6 cells/ml. Hybridoma antibodies can be produced in vitro and in vivo.įor production of monoclonal antibodies in vitro, hybridomas are expanded by transfer to 24 well tissue culture plates followed by 25 cm 2 flask and a 75 cm 2 flask containing suitable medium.

Furthermore, since similar rates of antibody production were obtained with either a soluble or particulate antigen, with different routes of inoculation and at different sampling sites, it is concluded that a general measure of secondary antibody synthesis has been demonstrated for one species of experimental animal.Ī correlation of the rate of diphtheria antitoxin formation with the determinations of toxoid decay in the lymph node indicates that the anamnestic production of antibody proceeds in at least two steps.
These findings confirm the results of a previous study on the kinetics of cholera antibody formation in guinea pigs (1, 4). A theoretical curve for serum antibody calculated from the above assumptions agrees well with the experimental data and strongly supports the hypothesis. The antibody pattern in the alum granuloma appears to reflect both the processes of synthesis and accumulation. The antitoxin content of the alum granuloma at the injection site, the draining lymph node and the blood was measured by the rabbit intracutaneous test and, whenever possible, by the quantitative precipitin technique.įrom the observed time-concentration curves it is postulated that lymph antibody is a measure of the rate of antibody production and that serum antibody represents the accumulation of antibody liberated into the blood reservoir. A study has been made of the secondary antibody response in guinea pigs immunized with purified diphtheria toxoid.
