No significant cross-reactivity or interference between Human PENK and analogues was observed.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBackground\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003ePreproenkephalin has 267 amino acids, as does proopiomelanocortin. Both genes contain 2 introns. In both, all the repeated enkephalin or melanotropin sequences are encoded by a single large exon (exon 3). Preproenkephalin mRNA encodes 4 copies of met-enkephalin, 2 copies of met-enkephalin extended sequences, and 1 copy of leu-enkephalin. Each copy is flanked by paired basic amino acids which are presumably recognized by the processing protease.\u003c\/p\u003e\u003cp\u003eThe corresponding amino acid sequence shows that the precursor is 267 amino acids long and contains 6 interspersed Met-enkephalin sequences and 1 Leu-enkephalin sequence. The precursor does not contain the sequences of dynorphin, alpha-neo-endorphin or beta-endorphin.\u003c\/p\u003e","brand":"Abbkine Scientific Co., Ltd.","offers":[{"title":"48 T","offer_id":53338625376621,"sku":"KTE61251-48T","price":339.0,"currency_code":"USD","in_stock":true},{"title":"96 T","offer_id":53338798358893,"sku":"KTE61251-96T","price":589.0,"currency_code":"USD","in_stock":true},{"title":"96 T×5","offer_id":53338798391661,"sku":"KTE61251-96TX5","price":2629.0,"currency_code":"USD","in_stock":true},{"title":"96 T×50","offer_id":53338798424429,"sku":"KTE61251-96TX50","price":24569.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/KTE61251.png?v=1778954742","url":"https:\/\/www.ebiohippo.com\/products\/human-proenkephalin-penk-elisa-kit-bhe13703467","provider":"BioHippo","version":"1.0","type":"link"}
