Overview<\/h3>\n

IGF-1 LR3 is a recombinant analog of human IGF-1 with two key modifications: an arginine substitution at position 3 (R3) and a 13\u2013amino acid N-terminal extension (Long, derived from methionyl porcine GH). These changes reduce binding affinity for the IGF binding proteins (IGFBPs), which extends free, bioavailable IGF-1 in research systems.<\/p>\n

Research Background<\/h3>\n

IGF-1 LR3 has been studied in research on cellular proliferation, muscle and tendon biology, and somatotropic axis pharmacology. Its altered IGFBP binding profile makes it a useful tool for studying IGF-1 receptor activation independent of binding-protein dynamics.<\/p>\n

Storage & Handling<\/h3>\n

Store lyophilized peptide at -20\u00b0C for long-term stability. Once reconstituted with bacteriostatic water, store at 2\u20138\u00b0C and use within recommended timeframes. Handle under sterile laboratory conditions and avoid repeated freeze-thaw cycles.<\/p>\n

Overview:<\/strong>
\nIGF-1 LR3 (Long R3 IGF-1) is a recombinant 83\u2013amino acid analog of human insulin-like growth factor-1 with reduced affinity for IGF binding proteins, leading to greater bioavailable IGF-1.<\/p>\n","protected":false},"featured_media":1000650,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[124,127],"product_tag":[],"class_list":["post-1000576","product","type-product","status-publish","has-post-thumbnail","product_cat-all-peptides","product_cat-metabolic-compounds","first","instock","shipping-taxable","purchasable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/bodyflexpeptides.com\/index.php?rest_route=\/wp\/v2\/product\/1000576","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bodyflexpeptides.com\/index.php?rest_route=\/wp\/v2\/product"}],"about":[{"href":"https:\/\/bodyflexpeptides.com\/index.php?rest_route=\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/bodyflexpeptides.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1000576"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bodyflexpeptides.com\/index.php?rest_route=\/wp\/v2\/media\/1000650"}],"wp:attachment":[{"href":"https:\/\/bodyflexpeptides.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1000576"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bodyflexpeptides.com\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_brand&post=1000576"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bodyflexpeptides.com\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_cat&post=1000576"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bodyflexpeptides.com\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_tag&post=1000576"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
