Preface
Over 2000 years ago in China, antibodies elicited by early forms of vaccination likely
playedamajorroleintheprotectionofthepopulationfrominfectiousagents.Vacci-
nation has been further developed in Europe and described by Edward Jenner in the
late-eighteenth century, then successfully implemented worldwide. The idea to use
theactiveingredientinthebloodofvaccinated(orimmunized)animalsorhumansfor
the treatment of diseases came a century later. It was made possible by a series of
discoveries,suchastherealizationthattheserumfromanimalsimmunizedwithtoxins,
for example, diphtheria toxin or viruses, is an effective therapeutic against the disease
causedbythesameagentinhumans.Inthe1880s,vonBehringdevelopedanantitoxin
(anti-body) that did not kill the bacteria but neutralized the bacterial toxin. The first
Nobel Prize in Medicine (1901) was given to him for the discovery of the serum
therapy.Acenturylater,22monoclonalantibodies(mAbs)areapprovedbytheUnited
States Food and Drug Administration (FDA) for clinical use, and hundreds are in
clinicaltrialsforthetreatmentofvariousdiseasesincludingcancers,immunedisorders,
and infections. The revenues from the top-five therapeutic antibodies reached $11.7
billion in 2006, and major pharmaceutical companies raced to acquire antibody
biotech companies with a recent example of MedImmune, Inc., which was acquired
for$15.6billionbyAstraZenecain2007.
This explosion of research and development in the field of therapeutic antibodies
prompted the publication of the MiMB volume Therapeutic Antibodies: Methods and
Protocols. The book’s major goal is to present a set of protocols useful for researchers
discoveringanddevelopingtherapeuticantibodies.Currentadvancesandfuturetrends
in the antibody therapeutics are analyzed in the lead-in review article. The road from
identificationorselectionofappropriatetargetstoantibodiesinclinicaluseisdivided
into five major stages: (1) recombinant antigens, (2) antibody libraries, (3) antibody
discovery,(4)antibodyengineering,and(5)antibodypreclinicaldevelopment.Alsoa
low-cost antibody sequence database is described in the last chapter. Representative
protocolsforeachstagearewrittenbyleadingexpertsfromacademiclaboratoriesand
biotechnology companies. Protocols for antibodies as reagents are not included
becauseof theexistence ofexcellent books onmethods for such antibody generation
andcharacterization.
PartIincludesseveral methodsthathavebeensuccessfullyemployedtoproduce,
purify,andcharacterizesolublesecretedversionsofseveralviralenvelopeglycoproteins
successfully used as antigens for selection of neutralizing human monoclonal antibo-
dies.PartIIdetailsmethodstocreatephagelibrariesofhumansyntheticsingle-chain
antibodies, human antibody domains (V ), and rabbit antibodies. It also details a
H
method for construction of a large na¨ıve human Fab library, which was successfully
usedforselection ofpotent neutralizingantibodiesagainstviruses andcancer-related
proteins. Part III contains protocols for selecting antibodies against intracellular
targets,specificinternalizationfragments,antibodieswithbroadspectrumofbinding

and neutralization, non-aggregating V binders from synthetic phage libraries, and
H
IgGs from combinatorial libraries expressed in Escherichia coli. It also contains
advancedmethodsforhigh-throughputscreeningofsingle-chainantibodies,identifi-
cationoffullyhumanantigen-specificantibodyrepertoirefromplasmacells,andrapid
screeningplatformforstabilizationofsingle-chainantibodies.PartIVcoversmethods
for antibody engineering including affinity maturations, construction of tetravalent
bispecific antibodies, deimmunization of antibodies, and preparation and character-
ization of antibody conjugates for targeted cancer therapies. Part V describes several
aspects of the antibody preclinical development including high-level production for
laboratory studies, scaling up and production for preclinical animal studies, in vitro
antibody potency and breadth of virus neutralization, and in vivo methods for estab-
lishingsynergybetweenantibodiesincancertherapyinmiceandpassiveimmunization
againstHIV-1inmacaques.
