Immunological Methods for Analysis of Recombinant Proteins
1998
We want to introduce researchers to techniques that help to solve some problems in the work of the molecular biologist. After transformation of recombinant DNA in E. coli cells many clones are usually produced, and the same situation appears if recombinant DNA expression libraries are available. Furthermore, if appropriate monoclonal or polyclonal antibodies are available, the method of immunoscreening of colonies for direct immunological detection of translational products of cloned genes can be used. Selected clones could be chosen for further studies such as determination of their primary structure by DNA sequencing and for characterization of an appropriate expressed protein.
Cloning of cDNAs coding forCandida albicanscell surface proteins
1995
Two cDNA libraries were constructed from mRNAs obtained from yeast cells and germ-tubes of Candida albicans in lambda gt11. Immunoscreening with polyclonal antibodies raised against cell wall components allowed the detection of 29 positive clones. Two of these clones were selected for their specific reactivity with antisera either from yeast (clone 11Y) or germ-tubes (clone 24M). cDNA fragments were isolated by the digestion of lambda DNA with EcoRI. Southern blot analysis with these fragments as probes demonstrated homology with C. albicans DNA, and by Northern analysis two mRNAs transcripts were detected with sizes of approximately 1·5 kb for 11Y and 1·1 kb for 24M. Both transcripts were …
