E. coli hücrelerdeki smFISH yöntem2kullanarak farklı genler transkript sayısı bizim laboratuvar olarak ölçülen var. Kısacası, bu yordamı aşağıdaki adımlardan oluşur: hücre fiksasyon, membranlar sonda penetrasyon için izin vermek için permeabilization sonda hibridizasyon ve örnek bir standart floresan mikroskop kullanarak görüntüleme. Bu yordam önceden yayınlanmış olanlar bazı değişiklikler6,7,</s...

Stochasticity gen ifadesinin temel ve kaçınılmaz bir unsuru ve hücre-hücre heterojenite1, transkriptler ve proteinler2,3düzeyinde hem de açmaktadır. İyi tanımlanmış koşullar altında hücreler arasında değişkenlik miktarının benzersiz bir pencere gen ekspresyonu ve onun yönetmelik altında yatan temel işlemleri halinde sunmaktadır. Bakterilerde hücre-hücre heterojen bir önemli kaynağı transkripsiyon düzeyinde gerçekleşir. Transkript numaraları sadece stochasticity transkripsiyonu, aynı zamanda düzenleme gibi çoğu işlemleri nedeniyle küçük RNA'ların ve RNAases2tarafından değişir. Doğrudan erişim Bu heterojenlik nicel bir moda bir fluorescently smFISH içinde belirli bir gen bireysel Tutanaklar etiketleyerek yoludur. Bu metodoloji algılama ve belirli RNA molekülleri, hücre altı yerelleştirme sabit, bireysel bakteri hücreleri4sağlar. mRNA'ların seçmeli olarak faiz5,6transkript bağlamak için tasarlanmış fluorescently etiketli ~ 20 Bankası-uzun oligonucleotides bir dizi melezleşmiştir. Birden çok etiket yukarıda arka plan Floresans algılama sağlar ve bireysel mRNA molekülleri kırınım-sınırlı noktalar bir floresan mikroskop altında7 (bkz: şekil 1) olarak görünür. MRNA molekülleri, tamamlayıcı oligomer probları ikincil fluorescently etiketli muhabir teknikleri8kullanarak algılanır konjuge anhidridler (örneğin, biotin veya digoxigenin) taşımak etiketleme için diğer yaklaşım vardır.
Tutanaklar, ek olarak smFISH hakkında kantitatif bilgi başka yöntemleri de vardır. Kuzey gibi bazı leke veya kantitatif PCR, toplu yoklama ve böylece ne mRNA kopya sayısı ne de tek tek hücreler içindeki konumlarını ölçebilirsiniz. Bu nedenle bu yöntemler hücre hücre değişkenlik ölçmek uygun değildir. Hata-sağlam Floresans in situ hibridizasyon (MERFISH) hem RNA'ların kopya numarası hücrelerindeki hem de denilen hücre içi konumlarını miktar multiplexed için izin veren bir son görüntü tabanlı teknik geliştirilmiştir. MERFISH tanımlanmış bir arada sabit sayıda Oligonükleotid fluorescently etiketli sonda gelen oluşan benzersiz bir barkod atama temel alır. Bu barkodları smFISH ölçümleri sıralı tur olarak okunduğu, photobleaching ile hibridizasyon, böylece artan işlem hacmi iki büyüklük9,10tarafından aşağıdaki her yuvarlak. Bu teknik bir otomatik akışkan sistemi ve sonda kümesinin uygun tasarım gerektirir.
Birden çok floresan Stokastik optik imar mikroskobu (fırtına)11gibi roman süper çözümleme teknikleri ile birlikte bireysel transkript etiketlerine göre ile birlikte çözünürlükte panolarında bir artış sağlar transkript hücre altı lokalizasyonu. FIRTINADA, Floresans emisyon (yanıp sönen) prob molekül başına birden fazla döngüleri için uygun kombinasyonu floresan problar ve görüntüleme arabellek sağlar. Fırtına da E. coli transcriptome görüntü ve aynı anda transkriptlerinizin faiz12etiketleme tarafından RNA, genom çapında mekansal organizasyonu gözlemlemek için kullanılabilir.
Yukarıda gözden tüm tek hücreli yöntemleri sabit hücrelerdeki transkript görüntüleme üzerinde temel alır. Bu nedenle, onlar transkript hücrelerdeki Kinetik özelliklerinin ile ilgili herhangi bir bilgi vermeyin. Transkript canlı hücreleri13izlemek için mRNA'ların ilgi siteleri bağlama, bir dizi gen füzyonu tarafından etiketli. Bu ikinci o zaman bakteriyofaj gibi yeşil flüoresan protein (GFP)10,14,15floresan bir protein için erimiş MS2 kat protein gibi bir RNA-bağlayıcı protein tarafından tanınır.
Burada DNA probları fluorescently etiketli smFISH deneyler, kullanmak için bir dizi bireysel mRNA'ların özellikle E. colietiketleme yöntemi açıklanmaktadır. Ayrıca, aynı etiketleme şeması fırtına ölçümleri ile küçük değişiklikler için kullanılan gösterir.

method for labeling transcripts in individual escherichia coli cells for single-molecule fluorescence in situ hybridization experiments

Bir yöntem bireysel mesajcı RNA (mRNA) Tutanaklar tek molekül Floresans in situ hibridizasyon (smFISH) E. colideneylerde kullanmak için sabit bakterilerde etiketleme için tanımlanır. smFISH mRNA kopya numarası ilgi genlerin hücre hücre değişkenlik ölçümü transkriptleri hücre altı konumunu sağlar. Ana adımları bakteriyel hücre kültürü fiksasyonu, hücre zarları permeabilization ve hedef transkript hibridizasyon setleri ile piyasada kısa Oligonükleotid fluorescently etiketli probları vardır. smFISH farklı floresan işaretleri arasında spektral örtüşme tarafından uygulanan sınırlamaları ile aynı hücrede birden çok gen transkript görüntüleme izin verebilirsiniz. Aşağıda resimli Protokolü tamamlanmasını takiben, hücreleri kolayca düşük yoğunluktaki floresan için uygun bir fotoğraf makinesi ile birleştiğinde bir mikroskop kullanarak yansıması. Bu görüntüler, segmentasyon faz kontrast kare veya hücre zarı boyama, elde edilen hücre dağılımları ile birlikte mRNA kopya numarası dağıtım örneği açık kaynak veya özel olarak yazılmış yazılım kullanarak hücre hesaplama sağlar. Burada açıklanan etiketleme yöntemi Ayrıca resmi transkript Stokastik optik imar mikroskobu (fırtına) ile uygulanabilir.

Biz smFISH ölçümleri galK ve sodB transkript E. coli hücrelerdeki yürüttü. Transkript belirli dizileri için hedef sıra, floresan molekülünü Birleşik her sonda tamamlayıcı bir dizi melezleşmiştir (malzemelerin tabloya bakın).
