Biz pek çok peptid fragmanları insan sindirilmemiş tükürük var olduğunu bulduk.

Saptanmamış yarılma bölgeleri olan peptitler üretimine katkıda bulunan bir çok faktör var olabilir. Örneğin bazı peptit parçaları insan tam tükürük doğal olarak mevcut olabilir. C-termini...

sampling human indigenous saliva peptidome using a lollipop-like ultrafiltration probe: simplify and enhance peptide detection for clinical mass spectrometry

Insan tükürük proteom ve peptidome 1-2 ortaya sürülmüş olsa da onlar majorly triptik tükürük proteinleri sindirir identifiye edildi. Insan tükürük yerli peptidler, hastalığın tanısında hastalığın ilerlemesini tahminde ve terapötik etkinlik izlenmesi için potansiyel değerlerini sağlamak yana eksojen enzimler ile önceden sindirim olmadan insan tükürük yerli peptidome belirlenmesi, önem kazanmaktadır. Uygun örnekleme insan yerli tükürük peptidome belirlenmesi geliştirilmesi için önemli bir adımdır. 3-4 enkaz kaldırmak için santrifüj içeren insan tükürük örnekleme Geleneksel yöntemler çok zaman alıcı klinik kullanım için geçerli olması olabilir. Ayrıca, santrifüj enkaz kaldırma enfekte patojenlerin en temiz ve genellikle düşük bolluk peptidome belirlenmesine engel yüksek bolluk proteinleri kaldırmak mümkün olabilir. Konvansiyonel proteomik yaklaşımlar priin-jel sindirim ile konjugasyon Marily kullanan iki boyutlu jel elektroforezi (2-DE) jeller birçok tükürük proteinleri 5-6 belirleme yeteneğine sahiptirler. Ancak, bu yaklaşım genellikle düşük bolluk peptid / protein tespit etmek için yeterince duyarlı değildir. Sıvı kromatografisi-kütle spektrometresi (LC-MS) tabanlı proteomik önce 2-DE ayrımı olmadan proteinler tespit edebilir bir alternatiftir. Bu yaklaşım, yüksek hassasiyeti sağlasa da, genel olarak önceden Örnek ön-fraksiyonasyon 7 ve zor bir hale getirir klinik kullanım için tripsin ile ön-sindirim ihtiyacı vardır. Numune hazırlama nedeniyle kütle spektrometresi de engel aşmak için, kılcal ultrafiltrasyon (CUF) probları 8-11 denen bir teknik geliştirdik. Laboratuvar verileri CUF probları dinamik ve minimal invaziv şekilde 8 hayvanlarda çeşitli mikro gelen in vivo protein yakalama yeteneğine sahip olduğunu gösterdi -11. Negatif basınç numune alma sırasında çekilerek sadece şırınga ile oluşturulan bu yana hiçbir santrifüj gereklidir. LC-MS ile birlikte CUF probları başarıyla triptik-sindirilmiş protein 8-11 belirledik. Bu çalışmada, kolaylıkla insan oral kavite sığabilecek bir lolipop benzeri ultrafiltrasyon (LLUF) prob oluşturarak ultrafiltrasyon örnekleme tekniği yükseltti. Tripsin sindirim olmaksızın LC-MS ile doğrudan analizi keşif sahasında insan tükürük çeşitli proteinlerin elde edilen pek çok peptid fragmanları içerir gösterdi. LLUF problar ile tükürük Örnekleme santrifüj kaçınılması ama etkili birçok büyük ve yüksek bolluk proteinler kaldırıldı. Bizim kitle spektrometrik sonuçlar çok düşük bolluk peptitler LLUF problar ile daha büyük proteinler filtreleyerek sonra saptanabilir hale geldiği gösterilmiştir. Düşük bolluk tükürük peptidlerin Algılama kromatografisi ile birden fazla adım örnek ayrılması bağımsız oldu. Klinik uygulama için, LLUF probları dahilLC-MS ile d potansiyel tükürük hastalığın ilerlemesini izlemek için gelecekte kullanılabilir.
