Abstract To overcome problems associated with Western blotting of denatured proteins, we have used quantitative immunoelectrophoretic techniques to perform functional analysis of the Neisseria gonorrhoeae common antigen. Using these techniques, we show (a) that Neisseria gonorrhoeae expresses an antigen that is cross-reactive with the common antigen of Pseudomonas aeruginosa and Legionella micdadei and with the GroEl-like protein of Chlamydia , and (b) that this N. gonorrhoeae common antigen has lectin-like activity and can be precipitated with three different sugars immobilized on agarose beads: α- d -glucosamine, maltose and fucose. 相似文献

An evaluation of social experience in the establishment of dominance-submission relationships was attempted using 20 animals in various constellations of 4. The establishment of rank-order in 5 groups of inexperienced heifers upon their first contact with strangers was compared with that in 20 groups consisting of the same animals in different arrangements upon their second to their fifth encounter with strangers. With experience, the various types of agonistic interactions were differently utilized, contact-forming and fighting time were reduced, the social order was more rapidly and firmly established, and fighting often dispensed with. 相似文献

The cloning of small GTP-binding proteins from Petunia hybrida was performed using a PCR-based strategy. Degenerate primers were designed from the DTAGQE and FMETSA consensus sequences. Three different cDNAs were amplified. The deduced polypeptide sequences PhPCRGP1 and PhPCRGP2 were homologous to RB11_HUMAN and PhPCRGP3 to RAB1A_HUMAN. Using PhPCRGP3 as a probe, 8 identical clones were selected from a Petunia leaf cDNA library. They all encode the same 22.5 kDa polypeptide, PhRAB1, able to bind GTP in vitro and 72% identical to RAB1A_HUMAN. Hybridizable mRNAs encoding PhRAB1 accumulated preferentially in opened flowers. 相似文献
