A tshuaj tiv thaiv ua haujlwm los ntawm kev cob qhia lub cev tiv thaiv kab mob kom paub txog thiab tawm tsam cov kab mob, xws li kab mob lossis kab mob. Los ntawm txhaj tshuaj cov antigens no rau hauv lub cev , lub cev tiv thaiv kab mob tuaj yeem kawm paub paub lawv zoo li cov neeg tawm tsam, tsim cov tshuaj tiv thaiv, thiab nco ntsoov lawv rau yav tom ntej.
Qhov tseeb, yuav muaj dab tsi tshwm sim thaum txhaj tshuaj tiv thaiv kab mob?
Cov tshuaj tiv thaiv kab mob muaj cov kab mob uas tsis muaj zog los yog tua tau nkag rau hauv koj lub cev, feem ntau yog los ntawm txhaj tshuaj . Koj lub cev tiv thaiv kab mob reacts rau tshuaj tiv thaiv zoo ib yam li nws yuav yog tias nws raug cuam tshuam los ntawm tus kab mob - los ntawm kev ua cov tshuaj tiv thaiv. Tom qab ntawd lawv nyob hauv koj lub cev, muab kev tiv thaiv rau koj.
Tsis tas li ntawd, tshuaj tiv thaiv muaj dab tsi? Cov tshuaj tiv thaiv muaj Cov kab mob nyob, tua kab mob, purified viral proteins, inactivated bacterial toxins, los yog kab mob polysaccharides. Ntxiv nrog rau cov immunogens, cov tshuaj tiv thaiv kab mob feem ntau muaj lwm yam khoom.
Kuj paub yog, cov tshuaj tiv thaiv puas nkag mus rau hauv cov hlab ntsha?
Cov tshuaj tiv thaiv kab mob tsis txawv. Txawm hais tias kev ntseeg yog qhov ntawd cov tshuaj tiv thaiv kab mob txhaj tshuaj ncaj qha mus rau hauv cov ntshav , lawv tau muab tshuaj tiag tiag rau hauv cov leeg los yog txheej ntawm daim tawv nqaij hauv qab lub dermis qhov twg lub cev tiv thaiv kab mob nyob thiab ncig raws li tshwm sim tom qab kab mob.
Dab tsi ntawm cov tshuaj tiv thaiv ua rau lub cev tiv thaiv kab mob?
Cov tshuaj tiv thaiv kab mob muaj ib daim ntawv tuag lossis hloov pauv ntawm cov kab mob uas ua rau cov kab mob, uas tau nkag mus rau hauv lub cev . Cov kab mob tuag lossis hloov pauv no nqa cov antigen tshwj xeeb. Qhov no ua rau lub cev tsis muaj zog lawv , tshwj xeeb tshaj yog cov qe ntshav dawb, los tsim cov tshuaj tiv thaiv ntxiv, uas lub hom phiaj thiab txuas rau cov antigen.

Dab tsi yog cov tshuaj tiv thaiv thiab lawv cuam tshuam nrog cov tshuaj tiv thaiv li cas?
Cov tshuaj tiv thaiv kab mob (immunoglobins) yog cov protein zoo li Y tsim los ntawm B hlwb ntawm lub cev tiv thaiv kab mob hauv kev teb rau kis rau antigens. Txhua cov tshuaj tiv thaiv muaj ib qho paratope uas paub txog ib qho epitope ntawm ib qho antigen, ua zoo li lub xauv thiab qhov tseem ceeb binding mechanism
Kev tiv thaiv dab tsi tshwm sim los ntawm kev txhaj tshuaj tiv thaiv?
Artificially tau txais kev tiv thaiv kab mob tuaj yeem tsim los ntawm tshuaj tiv thaiv, ib yam khoom uas muaj antigen. Ib qho tshuaj tiv thaiv ua rau cov lus teb thawj zaug tawm tsam antigen yam tsis ua rau cov tsos mob ntawm tus kab mob
