3,3′-Diaminobenzidine CAS:91-95-2

3,3′-Diaminobenzidine (DAB) ikemikari inoshandiswa zvakanyanya mu immunohistochemistry (IHC) uye immunocytochemistry (ICC) techniques staining. I chromogenic substrate inogadzira brown reaction product kana yasangana ne peroxidase enzymes, zvichiratidza kuvapo kwe target antigen.

DAB inowanzo shandiswa kufungidzira mapuroteni kana mamwe mamorekuru anodiwa mukati memasampuli ehupenyu, akadai sezvikamu zvenyama kana masero. Inogona kupa chiratidzo chiri munzvimbo uye chinoonekwa cheantigen, zvichibvumira vaongorori kuona nekuongorora kupararira kwayo nekuwanda kwayo.

Kushandiswa uye Mhedzisiro

Mhedzisiro ye3,3'-Diaminobenzidine (DAB) ndeyekugadzira ruvara rwebrown kana ikasangana nema enzymes eperoxidase. Kuchinja kweruvara uku kunobvumira kuona maantigens anotarisirwa kana ma biomolecules anofarira immunohistochemistry (IHC) uye immunocytochemistry (ICC) staining assays.DAB inowanzoshandiswa mukutsvagisa kwezvekurapa uye mashandisirwo ekuongorora kuti ione uye iwane maantigens chaiwo kana mapuroteni mukati memasampuli ebhayoloji. Nekuwedzera DAB se substrate uye reaction inotevera nema enzymes eperoxidase, brown precipitate inoumbwa panzvimbo yema antigens anotarisirwa. Kushandiswa kweDAB staining kunonyanya kubatsira mukudzidza zvirwere zvakasiyana-siyana nemamiriro ezvinhu. Inogonesa vaongorori nevanoongorora zvirwere kuti vaone uye vaongorore kugoverwa, kuwanda, uye nzvimbo yema biomolecules chaiwo mumatishu kana masero. Ruzivo urwu runobatsira kunzwisisa nzira dzezvirwere, kudzidza maitiro emasero, uye kuona zvinangwa zvinogona kuongororwa kana kurapwa. Uyezve, kudhirowa kweDAB kunogona kushandiswa mumhando dzakasiyana dzemamorekuru kuongorora kudyidzana kwemapuroteni nemapuroteni, kuona maitiro ekutaura kwemapuroteni, kuona kuvapo kwezviratidzo zvakananga, uye kuongorora kushanda kwenzira dzekurapa. Nekuda kwedhirowa rayo rakavimbika uye rakasimba, pamwe nekubatana kwayo nemaitiro akasiyana ekuona uye nzira dze microscopy, DAB yave chinhu chinoshandiswa zvakanyanya mukuongorora immunohistochemistry uye immunocytochemistry.
