A general method for chimerization of monoclonal antibodies by inverse polymerase chain reaction which conserves authentic N-terminal sequences

Chimerization of antibodies (Ab) by cloning the V (variable) regions encoding the light and heavy chains with degenerate oligodeoxyribonucleotide primers matching to framework region 1 and to the joining regions, leads to Ab with altered amino acids at the N-terminus compared to those of the parental Ab. This is due to N-terminal framework 1 sequences in the expression vectors [Larrick et al., Bio/Technology 7 (1989) 937–938; Le Boeuf et al., Gene (1989) 371–377; Orlandi et al., Proc. Natl. Acad.Sci. USA 86 (1989) 3833–3837]. This might lead to Ab with altered affinity to the antigen due to interaction of framework sequences with complementarity determining regions. Moreover, some V regions may be refractory to cloning by this procedure. Here, we describe a method to circumvent these potential problems. The V regions for both chains of the Ab are cloned by inverse polymerase chain reaction (PCR) with primers matching the known constant region sequences of the Ab. After sequencing, PCR fragments corresponding to the V regions of both chains are inserted in-frame into appropriate expression vectors leading to Ab with unaltered N-terminal sequences after expression in mammalian cells. The procedure is illustrated with an Ab directed against the β chain of the human interleukin-2 receptor.

MATE CHOICE IN THE WOOD FROG, RANA SYLVATICA.

Since Darwin's (1871) introduction of the theory of sexual selection, studies of mating associations have emphasized three patterns: (1) male-male competition (intrasexual selection) for control of females (Parker, 1970; Le Boeuf, 1974; Davies and Halliday, 1979; Wells, 1979), (2) male control of resources favored by females (Thornhill, 1976; Wells, 1977a; Howard, 1978), and (3) non-random mate choice by females (intersexual selection). Later refinements of Darwin's theory have focused on the differential investment of males and females in reproduction (Bateman, 1948), individual behaviors which maximize reproductive success (Trivers, 1972), and the ecological factors influencing patterns of mate choice (Orians, 1969; Borgia, 1979). Trivers (1972) and others (Bateman, 1948; Fisher, 1958; Williams, 1975) concluded that females generally have a much greater investment in reproduction and a higher certainty of parenthood than males and would be expected to be more discriminating in their choice of potential mates. Male reproductive success is generally limited by access to females and the number of female gametes fertilized. While natural selection in both sexes favors increased genetic representation in future generations (Williams, 1975), males are expected to maximize their reproductive success by increasing the number of matings, whereas females should choose higher quality mates. The major mechanism hypothesized that underlies patterns of sexual selection is that discriminating females control the reproduction of indiscriminate males. A fourth pattern of mating associations is non-random mate choice by males. Discussions of male choice are usually restricted to monogamous mating systems where males contribute an amount of parental effort that equals or exceeds that of females (Wilson, 1975) and in cases where sex role reversal occurs (Hohn, 1967; Smith, 1976). Otherwise males are assumed to lose little in indiscriminate matings (Bateman, 1948; Trivers, 1972; Williams, 1975). Few studies have examined the role of male choice in mating systems. This paper reports the importance of both male-male competition and male discrimination in the mating pattern of the wood frog, Rana sylvatica. Results of field observations and experiments performed with natural populations in woodland ponds, and of laboratory mate-choice experiments using males and females of varying ages, body sizes and geographic origins are presented. Experiments were designed to assess (1) relative importance of male and female choice, (2) effects of age and size on male reproductive success and (3) presence of non-random, assortative mating.

SEXUAL SELECTION AND DIMORPHISM IN TWO DEMES OF A SYMBIOTIC, PAIR-BONDING SNAPPING SHRIMP.

Highly polygamous and promiscuous species have been the subjects of most of the published studies on sexual selection (Bateman, 1948 [Drosophila]; Wiley, 1973 [sage grouse]; Le Boeuf, 1974 [elephant seals]; Parker, 1974 [dung flies]; Trivers, 1976 [Anolis]). Among monogamous species only the Arctic skua (O'Donald, 1972) and the feral pigeon (Burley, 1977) have been intensively studied with respect to the operation of sexual selection. Neglect of more monogamous species stems from the less spectacular differences between the sexes (Selander, 1972; Ralls, 1977) and from uncertainty as to whether sexual selection can operate in the absence of the potential for multiple matings (Mayr, 1972). This neglect is unfortunate as monogamous species offer valuable opportunities for examining sexual selection when the costs and benefits of mating adaptations are more closely balanced. This paper provides evidence for sexual selection in the snapping shrimp Alpheus armatus (Caridea, Alpheidae), an obligate symbiont of the Caribbean anemone Bartholomea annulata (Clarke, 1955). Adult shrimp are typically found in male-female pairs, a fact which suggests a primarily monogamous mating system. Data on sexual dimorphism in behavior and morphology, on differences between two areas in sexual dimorphism, and on the natural history needed to interpret these patterns will be presented. The overall purpose is to show how differences between the sexes in the importance of mate choice and in the potential for multiple matings interact with environmental constraints to produce sexual dimorphism.

The Cow on the Roof

On hearing this I think: that’s Milhaud’s The bull on the roof (Le boeuf sur le toit). Is it? Maybe it’s The cow on the roof and not The bull. Those two sound much alike The bull is being performed in New York we’re in Atlanta. That doesn’t matter. A piece of music doesn’t have a spatio-temporal location. The bull isn’t ever either here or there not even when it was being composed in Paris in 1919. A piece of music is an auditory pattern. An actual performance of a piece of music is a physical realization of a particular auditory pattern. Which auditory pattern is being given a physical realization here? Is it The bull or The cow? It sounds like The bull to me. It sounds like The cow to me. That’s because they sound alike.

Cocteau, Stravinsky, Brecht, And The Birth of Epic Opera

As ITS TITLE INDICATES, this paper is not intended to be a comprehensive survey of anti-Romantic and anti-Wagnerian tendencies in modern opera, but merely an attempt to evaluate certain affinities among Jean Cocteau's Le Coq et l’Arlequin, a collection of brilliant apercus about music and the theater, Stravinsky-Ramuz' Histoire du Soldat, Brecht-Weill's Dreigroschenoper, and the series of Anmerkungen which Brecht appended to the latter work. An historical outline of the epic trends on the musical stage of our day would necessarily entail consideration of such other key works as Erik Satie's Parade, Milhaud's Le Boeuf sur le Toif, Cocteau's Les Maries de la Tour Eiffel, Milhaud's La Creation du Monde, Sitwell-Walton's Fagade, and Claudel-Milhaud's Christophe Colomb, whose authors, instead of wishing to place the audience at once in a "narcotic atmosphere," "wanted to show how the soul gradually reaches music."
