    • The present invention provides synthetic 5'UTRs comprising a first polynucleotide fragment and a second polynucleotide fragment, wherein the first polynucleotide fragment comprises at least one splice site of a first eukaryotic gene, the second polynucleotide fragment comprises at least a portion of 5' untranslated region of a second eukaryotic gene, and the first polynucleotide fragment is located 5' of the second polynucleotide fragment. In one embodiment, the first polynucleotide fragment comprises the second intron of a sarcoplasmic/endoplasmic reticulum calcium ATPase gene and the second polynucleotide fragment comprises at least a portion of the 5' untranslated region (5'UTR) of a eukaryotic casein gene. The synthetic 5'UTRs are useful for increasing the expression of a transgene when positioned between a promoter and a transgene within an expression vector. The present invention also provides vectors comprising synthetic 5'UTRs and methods for increasing the expression of a transgene using synthetic 5'UTRs.

    • A group of modular cloning vector plasmids for the synthesis of a transgene or other complicated DNA construct, by providing a backbone having docking points therein, for the purpose of gene expression or analysis of gene expression. The invention is useful for assembling a variety of DNA fragments into a de novo DNA construct or transgene by using cloning vectors optimized to reduce the amount of manipulation frequently needed. The primary vector contains at least one multiple cloning site (MCS) and multiple sets of rare restriction and/or unique homing endonuclease ("HE") sites, arranged in a linear pattern. This arrangement defines a modular architecture that allows the user to place inserts into a transgene construct without disturbing the integrity of DNA elements already incorporated into the primary vector in previous cloning steps. Transgenes produced using the invention may be used in a single organism, or in a variety of organisms including bacteria, yeast, mice, and other eukaryotes with little or no further modification.
    • 为了基因表达或分析基因表达的目的,提供了一组用于合成转基因或其他复杂DNA构建体的模块化克隆载体质粒,通过提供其中具有对接点的骨架。 本发明可用于通过使用优化的克隆载体将各种DNA片段组装成从头DNA构建体或转基因,以减少经常需要的操作量。 主要载体包含至少一个多克隆位点(MCS)和多组稀有限制和/或独特的归巢内切核酸酶(“HE”)位点,以线性方式排列。 这种布置定义了模块化架构,其允许用户将插入物置于转基因构建体中,而不会干扰已经并入到先前克隆步骤中的主载体中的DNA元件的完整性。 使用本发明生产的转基因可以用于单一生物体,或者在包括细菌,酵母,小鼠和其他真核生物的多种生物体中,很少或不进行进一步的修饰。
