The \u03b1-subunit contains five disulfide bonds and two N-linked glycosylation sites (Asn\u2075\u00b2 and Asn\u2077\u2078). The \u03b2-subunit contains six disulfide bonds, two N-linked glycosylation sites (Asn\u00b9\u00b3 and Asn\u00b3\u2070), and four O-linked glycosylation sites in the C-terminal extension (Ser\u00b9\u00b2\u00b9, Ser\u00b9\u00b2\u2077, Ser\u00b9\u00b3\u00b2, Ser\u00b9\u00b3\u2078).<\/p>\n<ul>\n<li><strong>Subunit Architecture:<\/strong> \u03b1 (92 aa) + \u03b2 (145 aa), non-covalent heterodimer<\/li>\n<li><strong>Disulfide Bonds:<\/strong> 5 (\u03b1-subunit) + 6 (\u03b2-subunit), cystine knot motif<\/li>\n<li><strong>Glycosylation:<\/strong> 4 N-linked + 4 O-linked sites; sialic acid-capped<\/li>\n<li><strong>Molecular Formula:<\/strong> Glycoprotein \u2014 variable with post-translational modifications<\/li>\n<\/ul>\n<h3>Physicochemical Properties<\/h3>\n<ul>\n<li><strong>Appearance:<\/strong> White to off-white lyophilized powder<\/li>\n<li><strong>Isoelectric Point:<\/strong> pI ~3.5 (acidic, due to sialic acid residues)<\/li>\n<li><strong>UV Absorption:<\/strong> \u03bb<sub>max<\/sub> 280 nm (Trp\/Tyr residues)<\/li>\n<li><strong>Solubility:<\/strong> Freely soluble in aqueous buffers<\/li>\n<li><strong>Thermal Stability:<\/strong> Store lyophilized at 2\u20138\u00b0C; avoid repeated freeze-thaw cycles in solution<\/li>\n<li><strong>SDS-PAGE:<\/strong> \u03b1-subunit ~22 kDa, \u03b2-subunit ~38 kDa under reducing conditions (apparent MW includes glycan mass)<\/li>\n<\/ul>\n<p><strong>FOR RESEARCH USE ONLY \u2014 NOT FOR HUMAN CONSUMPTION<\/strong><\/p>","protected":false},"excerpt":{"rendered":"<p>Glycoprotein research compound \u00b7 Janoshik verified \u00b7 Lyophilized powder<\/p>","protected":false},"featured_media":8063,"template":"","meta":[],"product_brand":[],"product_cat":[189],"product_tag":[],"class_list":{"0":"post-7300","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-growth-hormone-peptides","8":"first","9":"instock","10":"sale","11":"taxable","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pandapeptides.com\/es\/wp-json\/wp\/v2\/product\/7300","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pandapeptides.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pandapeptides.com\/es\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pandapeptides.com\/es\/wp-json\/wp\/v2\/media\/8063"}],"wp:attachment":[{"href":"https:\/\/pandapeptides.com\/es\/wp-json\/wp\/v2\/media?parent=7300"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/pandapeptides.com\/es\/wp-json\/wp\/v2\/product_brand?post=7300"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pandapeptides.com\/es\/wp-json\/wp\/v2\/product_cat?post=7300"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pandapeptides.com\/es\/wp-json\/wp\/v2\/product_tag?post=7300"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
