Hybrid myeloma cell lines secreting monoclonal antibodies to tubulin have been prepared using rat myelomas and spleen cells from rats immunized with yeast tubulin. A comparison between the results obtained with the rat myeloma Y3-Ag 1.2.3., which secretes a light chain, and a new line, YB2/O, which does not, shows that they are both excellent parental lines(More)
The development of the monoclonal antibody YC5/45 HLK (YC5/HLK) against a 5HT-bovine seroalbumin immunogen and its application for immunocytochemistry is described. The YC5/HLK antibody is the product of a rat x rat hybrid myeloma, producing a heavy chain and two light chains. In hemagglutination tests, the antibody cross-reacts to entirety with dopamine,(More)
The tufted capuchin (Cebus apella) has been used in a number of comparative studies to represent a primate with craniofacial morphology indicative of hard-object feeding. Researchers have specifically referred to the tufted capuchin as a seed predator. Craniofacial features exhibited by the tufted capuchin, such as thick cortical bone in the mandibular(More)
1. The aims of this work were to discover the pathways of carbohydrate oxidation prior to and during thermogenesis by the club of the spadix of Arum maculatum, and whether there was coarse control of these pathways. 2. 14C02 production from [1-14C]-, [3,4-14C]-, and [6-14C]glucose, the detailed distribution of 14C from [1-14C]- and [6-14C]glucose, and the(More)
In vivo studies of jaw-muscle behavior have been integral factors in the development of our current understanding of the primate masticatory apparatus. However, even though it has been shown that food textures and mechanical properties influence jaw-muscle activity during mastication, very little effort has been made to quantify the relationship between the(More)
The African Plio-Pleistocene hominins known as australopiths evolved a distinctive craniofacial morphology that traditionally has been viewed as a dietary adaptation for feeding on either small, hard objects or on large volumes of food. A historically influential interpretation of this morphology hypothesizes that loads applied to the premolars during(More)
Monoclonal antibodies were produced following immunization of mice with either [Leu5]enkephalin-bovine serum albumin or [Met5]enkephalin-keyhold limpet hemocyanin conjugates. Two monoclonal antibodies coded NOC1 and NOC2, respectively, were derived. These monoclonal antibodies did not discriminate between Leu- and Met-enkephalin in either radioimmunoassay(More)
Recent biomechanical analyses examining the feeding adaptations of early hominins have yielded results consistent with the hypothesis that hard foods exerted a selection pressure that influenced the evolution of australopith morphology. However, this hypothesis appears inconsistent with recent reconstructions of early hominin diet based on dental microwear(More)
