I dont know if you already got a reply to this and I see Im very late but Im now looking at these videos. Europeans call C3 convertase - C4b2b and Americans call C3 Convertase - C4bC2a. Its jst a matter of country and Dr Najeeb uses European style, jst like me but you will find most textbooks made in US and so will use C2a instead of C2b.

Sir thanks a lot for posting all these videos on the you tube, and thank to you dear youtube which helped the several people to understand these lectures and then I must say that every candidate, who has studied it or just listened it will top in any seminar, examination and any thing.

Thanks a lot Dr. Najeeb, thanks a lot.

Actually if i say thanks several times it will be less.

May the almighty bless u and u carry on helping the candidates.

Thanks so much. I understand everything you say now. I just have one question: My textbooks say, it's C4b2a (and C4b2a3b), instead of C4b2b (and C4b2b3b) that makes the C3 (and C5) convertase. Why do you always say C2b?

thanks this is so much easier to listen to than my teachers

opsonization- tagging. C3b tags the molecule to notify the macrophage.
