HEPES buffer(4 - (2-hydroxyethyl) - 1-piperazine ethanesulfonic acid) es un tamp\u00f3n de \u00e1cido sulf\u00f3nico zwitteri\u00f3nico; Uno de los buenos 20 buffers. El tamp\u00f3n Hepes es ampliamente utilizado en el cultivo celular, principalmente porque puede mantener el valor de pH fisiol\u00f3gico mejor que el tamp\u00f3n de bicarbonato, que tambi\u00e9n se utiliza com\u00fanmente en el cultivo celular, aunque la concentraci\u00f3n de di\u00f3xido de carbono (producido por la respiraci\u00f3n aer\u00f3bica) cambia. Lepe Zuniga et al. Se ha informado de un proceso fotoqu\u00edmico no deseado en el que el tamp\u00f3n hepes produce per\u00f3xido de hidr\u00f3geno cuando se expone a la luz ambiental, lo que no es un problema en el tamp\u00f3n de cultivo celular a base de bicarbonato. Por lo tanto, se recomienda encarecidamente colocar la soluci\u00f3n que contiene tamp\u00f3n hepes en la oscuridad en la medida de lo posible para evitar la oxidaci\u00f3n.<\/p>","protected":false},"featured_media":4174,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[22],"product_tag":[24],"class_list":{"0":"post-4103","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-daily-chemicals","7":"product_tag-daily-chemicals","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product\/4103","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/comments?post=4103"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/media\/4174"}],"wp:attachment":[{"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/media?parent=4103"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product_brand?post=4103"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product_cat?post=4103"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/chemneo.com\/es\/wp-json\/wp\/v2\/product_tag?post=4103"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
