Provide M amp; eacute; all and ingredients to preserve tissue samples containing and amp; Aacute; nucleic acids including DNA at fr amp ambient temperature and without sampling; Iacute; or stored at fr amp; Iacute; o.despu amp; eacute; and then DNA in samples. Machining and analysis by M amp; eacute; all known, for example,Page: 1 1. One aspect of the invention is that M amp; oacute; n provides one aspect that M amp; eacute; all nucleic acids used for simple storage and / or processing and R amp; Aacute; de amp; Aacute; DNA and other nucleic acids, including but not including no car amp; Aacute; CTR limit; plants, tissues, smooth C amp; eacute; Lula bacteria contain PL amp; Aacute; smidos et al. Present invention; oacute; n includes ADEM amp; Aacute; s reagent and M amp; eacute; all human beings who use glycerine base acid-base method to process biological and ampere samples; oacute; logic and DNA can be used for PCBs without pure CI amp; oacute; additional sample n. Therefore,In one aspect, the invention provides all M amp; eacute; nucleic acids for simple processing and R amp; Aacute; de amp; Aacute; nucleic acids, such as DNA, from various sources, including but not including car amp; Aacute; CTR limante; plants, tissues, C amp smooth; eacute; bacteria Lula; Aacute; smidos with PL amp, Wait, wait, wait, etc.<;p>;SE PROPORCIONAN MÉ;TODOS Y COMPOSICIONES PARA PRESERVAR MUESTRAS TISULARES QUE CONTIENEN Á;CIDOS NUCLEICOS, INCLUIDO ADN, A TEMPERATURAS AMBIENTE Y SIN NECESIDAD DE MUESTREO EN FRÍ;O O ALMACENAMIENTO EN FRÍ;O. DESPUÉ;S DEL ALMACENAMIENTO, EL ADN PRESERVADO EN LAS MUESTRAS SE PUEDE ENTONCES PROCESAR Y ANALIZAR MEDIANTE MÉ;TODOS CONOCIDOS, P. EJ., PCR. LA PRESENTE INVENCIÓ;N PROPORCIONA EN UN ASPECTO, UN MÉ;TODO PARA EL ALMACENAMIENTO Y/O PROCESADO SENCILLO Y RÁ;PIDO DE Á;CIDOS NUCLEICOS TALES COMO ADN, A PARTIR DE VARIAS FUENTES, INCLUIDOS, SIN CARÁ;CTER LIMITANTE
