Dephtheria anti-toxin is preparation containing antitoxic globulins that they have the power of specifically neutralizing the toxin formed by Cornebacterium diphtheria.
Measure all the responses are calculated the result of the assay by std statistical method.
Ratio between two dose of test and two dose of standard should be equal This ratio kept constant through out the assay. Oestrogen progesterone and prolactin — responsible for production of milk by memory gland but milk ejection require oxytocin. Measure all the response and calculate the result of the assay by standard statistical method. Dilute 25ml of basal medium stock solution with equal volume of H2O sterile in autoclave.

P otency of rabies vaccine is determined by comparing a lethal intra-cerebral dose of a pf virus with the dose lf the standard preparation of rabies vaccines necessary to give for same protection.
Then they are incubated or about 24 hours at about and the diameter or areas of the circular inhibition zones are measured. In order to view it, please contact the author of the presentation. Thanks for shearing about this I thinks its very hopeful post and very important post for us. P response Dose should cause decrease in B.

Similarly record the contraction of test preparation as standard. The potency of diphtheria anti-toxin is determined by comparing the dose necessary to protect guinea-pig or rabbits against the erythrogenic effect of a fixed dose of the standard preparation of diphtheria anti toxin necessary to give the same protection.
Allow the mixtures to stand at room temperature, protected from light, for 15 to 60 minutes.
Tetanus anti-toxin is a preparation containing antitoxic globulins that have the power of specifically neutralizing the toxin formed by clostridium tetani. It is obtained by fractionation from the serum of horses or other mammals that have been immunized against diphtheria toxin.
