Although an Rh cDNA has been previously cloned, there is no information on which Rh antigenic protein it encodes. Using polymerase chain reaction (PCR) amplification, we have identified this original Rh clone, here designated Rh21, and an additional Rh cDNA clone, Rh13, that is 96% nucleotide- and 92% amino acid-identical to Rh21, with the substitutions scattered throughout the sequence. A molecular genetic approach was used to match this Rh clone with an Rh specificity. <strong>The mRNA transcript for Rh13 was present in reticulocytes from RhD-positive individuals, but was absent from the reticulocytes of RhD-negative individuals. <\/strong>Using conventional screening of genomic libraries, as well as PCR cloning, partial genomic clones for these two Rh cDNAs were obtained. Based on PCR analysis and Southern blots, the Rh21 gene was present in all individuals, but an intact Rh13 gene was only present in RhD-positive and not RhD-negative individuals. Thus, by correlating the presence of Rh mRNA and gene sequences with individual Rh phenotypes, we were able to establish that the new Rh13 cDNA clone represents the RhD protein.<br><\/p>\n\n\n\n<figure class=\"wp-block-embed-wordpress wp-block-embed is-type-wp-embed is-provider-rh-negative-blood-and-people\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"iJZxzrjAlF\"><a href=\"https:\/\/www.rhesusnegative.net\/staynegative\/what-is-cloning\/\">My answer to the question &#8220;Can Rh negative blood be cloned?&#8221;<\/a><\/blockquote><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; clip: rect(1px, 1px, 1px, 1px);\" title=\"&#8220;My answer to the question &#8220;Can Rh negative blood be cloned?&#8221;&#8221; &#8212; The Rh Negative Blog\" src=\"https:\/\/www.rhesusnegative.net\/staynegative\/what-is-cloning\/embed\/#?secret=AZUyo6KOBK#?secret=iJZxzrjAlF\" data-secret=\"iJZxzrjAlF\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div><\/figure>\n<div style=\"padding-bottom:20px; padding-top:10px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/static.hupso.com\/share\/buttons\/share-medium.png?w=640&#038;ssl=1\" style=\"border:0px; padding-top:5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Pinterest\",\"Linkedin\");var hupso_background_t=\"#EAF4FF\";var hupso_border_t=\"#66CCFF\";var hupso_toolbar_size_t=\"medium\";var hupso_twitter_via = \"datebytype\";var hupso_image_folder_url = \"\";var hupso_twitter_via=\"datebytype\";var hupso_url_t=\"\";var hupso_title_t=\"Can Rh negative blood be cloned?... another explanation:\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>","protected":false},"excerpt":{"rendered":"<div style=\"padding-bottom:20px; padding-top:10px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img src=\"https:\/\/static.hupso.com\/share\/buttons\/share-medium.png\" style=\"border:0px; padding-top:5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Pinterest\",\"Linkedin\");var hupso_background_t=\"#EAF4FF\";var hupso_border_t=\"#66CCFF\";var hupso_toolbar_size_t=\"medium\";var hupso_twitter_via = \"datebytype\";var hupso_image_folder_url = \"\";var hupso_twitter_via=\"datebytype\";var hupso_url_t=\"\";var hupso_title_t=\"Can Rh negative blood be cloned?... another explanation:\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>Here is a random answer from Quora: Red blood cells don\u2019t have neuclei.
