No significant cross-reactivity or interference between Human PZP and analogues was observed.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBackground\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003ePregnancy zone protein (PZP), one of the major pregnancy-associated plasma proteins, was described by Smithies (1959) who used zone-electrophoresis in starch gels. PZP is a prominent constituent of late-pregnancy sera. In healthy, nonpregnant females and in males, PZP is present in trace amounts only: females, 10-30 mg\/l; males, less than 10 mg\/l. During pregnancy, PZP levels may reach 1000-1400 mg\/l just before term. Sottrup-Jensen et al. (1984) showed that PZP closely resembles alpha-2-macroglobulin in structure. Both have a quaternary structure of 2 covalently bound 180-kD subunits which are further noncovalently assembled into a tetramer of 720 kD. Amino acid sequence of the 2 proteins are extensively homologous.\u003c\/p\u003e","brand":"Abbkine Scientific Co., Ltd.","offers":[{"title":"48 T","offer_id":53338618167661,"sku":"KTE61009-48T","price":339.0,"currency_code":"USD","in_stock":true},{"title":"96 T","offer_id":53338775028077,"sku":"KTE61009-96T","price":589.0,"currency_code":"USD","in_stock":true},{"title":"96 T×5","offer_id":53338775060845,"sku":"KTE61009-96TX5","price":2629.0,"currency_code":"USD","in_stock":true},{"title":"96 T×50","offer_id":53338775093613,"sku":"KTE61009-96TX50","price":24569.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/KTE61009.png?v=1778954716","url":"https:\/\/www.ebiohippo.com\/products\/human-pregnancy-zone-protein-pzp-elisa-kit-bhe13703225","provider":"BioHippo","version":"1.0","type":"link"}
