Maryland 20205 ogy, New York University Medical Cen- ter, New York, New York 10016 Preface Progress in interferon research, as in other areas, has reflected ad- vances in the development of new biological and chemical technologies. The methods described in Volumes 78 and 79 of "Interferons" reflect these achievements. By the early 1970s, basic studies on interferon induc- tion allowed the production of small amounts of interferon so that studies on its purification could begin. Of the three classes of interferon (fibro- blast, leukocyte, and immune), fibroblast and leukocyte interferons were the focus of attention in many laboratories. The methods for purifying these interferons are described in Volume 78. With the development of sensitive methods for the assay of amino acids and peptides, the application of high-performance liquid chromatog- raphy (HPLC) to protein purification was convenient and feasible, partic- ularly with substances that were available in minute amounts. The purifi- cation of interferon by reverse and normal phase HPLC was the first achievement of the purification of proteins by these high-performance procedures. Since then, numerous other proteins have been purified by HPLC with the use of these same techniques. As has been illustrated by additional examples, achievements in interferon research, as in this case, initiated the foundations for achievements in other areas. Even though some of the interferons were purified, only small amounts were available. However, it was possible to determine their amino acid composition, peptide maps, and some of their amino acid se- quences even with picomole to nanomole (0.2 to 02 ~g) amounts. The sec- tions in Volume 79 describe these methods. After the development of assays that could detect the synthesis of bio- logically active interferons in cell-free extracts and by microinjection directly into intact cells from isolated mRNA, it was feasible to consider cloning the DNA coding for these molecules. The methods leading to and including the construction and identification of DNA recombinants con- taining the interferon-coding sequences are described in Volume 79. As a result of the rapid application of these techniques, the complete amino acid sequences of human fibroblast and several leukocyte interfer- ons are now known (see Figs. 1 and 2). Both of these have been expressed in bacteria. Recombinant leukocyte interferon has been purified to homo- geneity and has been in clinical trial for about seven months. The isolation of monoclonal antibodies to leukocyte interferon was instrumental in the effective purification of recombinant human leukocyte interferon as well as in the development of convenient immunoassays for the detection of leukocyte interferon. Crystals of recombinant interferon have been ob- tained and will enable the elucidation of their tertiary structure by X-ray XX PREFACE 5' 1S $I0 02S 12S mec chr ash tys cys ueZ ueZ ~tn ire ala leu leu leu cys phe 8er Chr chr ala leu set TEM gE$ t~ NSA GTA CCA CAA GAA TGT CTC CTC AAC TTA CG CTC GTC GTT CGT CTT CCT T~A ACA TCG TTC CCT GTA CGA CAT CAA 50 01 02 LEO LKU GLY PHE LEU GLN ARG SER SER ASN PH~ CLN CYS GLN LYS LEU LEU TRP GLN LEU ASN GLY ARG LgU ~s~GLU GTT TTC AGG CTT ATC AAC AGA CGA CG~ TAA TTT CA6 TGr CAG AAG CTC CT6 TGG CAA TTG AAT GGG AGG CTT OOl o3 40 50 TYR GYS LEU LYS PSA ARG MET ASN PHE ASP ILE PRO GLU GLU ILE LYS GLN LEU GLN GLN PHK GIN LYS GLU ASP TAT CGT CTC 6AA CAG GGA GTA CAA TTr CAG CTA rCC GAG GAG TTA GAA 6AC GTC GAC GAC CTT GAC GAA GAG CAG 002 60 07 ALA ALA LEU THR ILE TYR GLU MET LEU GLN ASN ILE PHE ALA ILE PHE A~G GLN ASP $EK SEK SEg Trig GLY TRP CCG ACG GTT CCA CTA FAT GAG GTA CT5 GAC CAA CTA TTT TCG TTA CTT AGA AAC TAG ACr TCT CGA TCA CGG ~ST 052 3oo 80 90 i00 ASN GLU tHE ILK VAL GLU ASN LEO LEU ALA ASN VAL TYR HIS GLN ILK ASN HIS LEU L~$ THK VAL LEU GLU GLU TAA GAG TCA TTA Gr GAG CAA CTC GTC TCG TAA CTG TAT TAC GAC ATA CAA TAC 6TC GAA ACA crG cr6 AAG AAG 053 ll0 o21 LYS LEU GLD LYS GLU ASF PHE THR ARG GLY LYS LEU MET SE~ SER LKU HIS LEU LYS ARG TYK TYK GLY ARG ILE AAA CrG GAG AAA GAA GAT TrT ACC A~G GGA AAA CTC GTA CGA TGA GTC CAC GTC AAA AGA TAT TAT GGG GGA ATI 400 054 031 140 150 ~U HIS ~YR UEL LYS ALA LYS GLU TYR SER HIS CYS ALA TRP TflR ILE VAL ARG VAL GLU ILE LKU ARG ASN PHE GTC TAC CAT GTC GAA CCG GAA GAG CAT TGA CAC IGT CCG GGT CCA ATA C!G AGA GT6 AAG CTA ATC GGA CAA TTT 005 061 I66 TYR File ILE ASN AI~G UED THR GLY TYR LEO ARG ASN END CAT CTT TTA CAA AGA TTC ACA TGG CA!

Despite these achievements, much needs to be learned about the biological activity, mode of action, and the clinical efficacy of the interferons. The availability of sufficient amounts for these studies will undoubtedly lead to new insights during this next phase of interferon research. Very much needs to be learned about the "old" interferons, and we will certainly have some additional new ones in the future. The methods in these volumes cover the gamut of these paths. The contributors to these volumes have spent much time and effort in preparing detailed reports of their methodologies. I am grateful to them all for their many excellent contributions. The staff of Academic Press has been most efficient and supportive throughout this undertaking. Drs. Colowick and Kaplan have provided much sound advice since the time these volumes were initiated. Many colleagues and associates have given me numerous useful suggestions.
