Gametic Differentiation
A structural and biochemical study is presented concerning the agglutination of gametic flagella, the initial step in the mating reaction of Chlamydomonas reinhardtii. An alteration in the distribution of the intramembranous particles revealed by freeze-fracturing of flagellar membranes is shown to accompany gametic differentiation in both mating types. The isolation and electrophoretic analysi...
متن کاملVisceral Lesions in “Yellow” Mice ‡
OR HIGH-CARBOHYDRATE DIETSt "Yellow" mice such as those of strain YBR/Wi are represented by two genotypes which differ, as far as is known, in regard to one gene. Individuals possessing the Y' gene are yellow coated and become obese when fed enriched diets; individuals not possessing the Y' gene are grey coated and do not become obese when fed such diets.8'8 "' In yellow-coated animals, food co...
متن کاملBasics of gametic imprinting.
The fundamental assumption of Mendelian genetics is that behavior of an allele is identical whether it arrives to a zygote through paternal or maternal germline pathway. Gametic imprinting phenomena discovered and studied in mammals show limitations of the classical view in special cases. Two sources of evidence were essential to describe gametic imprinting. The first approach based on genetic ...
متن کاملInfluence of DOTA chelators on radiochemical purity and biodistribution in xenografted mice of 177Lu- and 90Y-Rituximab
Introduction This work presents a comparative biological evaluation of 90Y- and 177Lu- labelled DOTA-SCN and DOTA-NHS conjugated to Rituximab in tumour-bearing mice. Materials and methods Two DOTA derivatives, p-SCN-Bn-DOTA and DOTA-NHS-ester were conjugated to Rituximab and then freeze-dried kit formulations were prepared, as previously described [1]. Tissue distribution was investigated in t...
