Characterization of recombinant human interleukin-2 with micromethods |
abstract |
Highly purified recombinant human interleukin-2, expressed in Escherichia coli, was analyzed by micromethods. N-Terminal sequence analysis showed that methionine at position 0 was found in 90% of the molecules and not completely removed in post-ribosomal processing. A complete peptide map of the reduced and S-carboxymethylated protein was obtained by high-performance liquid chromatography after tryptic digestion, and the fragments were identified by amino acid analysis and automated Edman sequence analysis. Using a double-label S-carboxymethylation procedure, it was determined that there is a disulfide linkage between the cysteine residues at positions 58 and 105. The third cysteine residue at position 125 was found to be present as the free sulfhydryl. |

A complete peptide map of the reduced and S-carboxymethylated protein was obtained by high-performance liquid chromatography after tryptic digestion, and the fragments were identified by amino acid analysis and automated Edman sequence analysis. Using a double-label S-carboxymethylation procedure, it was determined that there is a disulfide linkage between the cysteine residues at positions 58 and 105. The third cysteine residue at position 125 was found to be present as the free sulfhydryl.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lahm, H.-W.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Stein, S.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Journal of Chromatography A</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">326(1985), Seite 357-361</subfield><subfield code="w">(DE-627)NLEJ17403282X</subfield><subfield code="w">(DE-600)1491247-8</subfield><subfield code="x">0021-9673</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:326</subfield><subfield code="g">year:1985</subfield><subfield code="g">pages:357-361</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/S0021-9673(01)87461-6</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">326</subfield><subfield code="j">1985</subfield><subfield code="h">357-361</subfield></datafield></record></collection>
