Most reverse transcription kits use MMLV retroviral reverse transcriptase to copy RNA into cDNA, but these enzymes lack strong strand displacement activity, so cDNA synthesis can be directly blocked by the tightly bound guide RNA (gRNA) itself. With bound gRNA preventing MMLV RTs from reading through the guide-binding region, RT-qPCR amplicons spanning or sitting just upstream of the gRNA site can be suppressed as a result, artificially indicating knockdown of the target gene. This pervasive effect is observed across RNA-targeting CRISPR systems, including Csm, PspCas13b, and CasRx.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Advantages\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccurate CRISPR KO\/KD quantitation:\u003c\/strong\u003e UltraMarathonRT's intrinsic helicase reads straight through bound guide RNA, giving you accurate knockdown quantification regardless of system employed or amplicon location.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Primer Design:\u003c\/strong\u003e Produces full-length, end-to-end cDNA in a single pass, so downstream qPCR primer pairs can be chosen anywhere along the target transcript without loss of signal — unlike non-processive retroviral RTs, which show widely different \u003cspan style=\"mso-comment-continuation: 1;\"\u003eC\u003csub\u003et\u003c\/sub\u003e\u003c\/span\u003e values depending on primer position.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust Performance: \u003c\/strong\u003eExceptional sensitivity and efficiency, ideal for detecting low-abundance RNA, viral RNA, non-coding RNAs, long RNAs, and even highly structured RNAs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Inhibitor Tolerance: \u003c\/strong\u003eMaintains full activity in the presence of inhibitory compounds potentially found in biological sample preparation, including ethanol (resistant to 10%), isopropanol (resistant to 5%), TRIzol (resistant to 0.7%), formalin (resistant to 0.0025%), ammonium acetate (resistant to 50 mM), bile salts (resistant to 0.05%), and hematin (resistant to 10 µM).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad Dynamic Range:\u003c\/strong\u003e Reverse transcribes RNA input from 1 pg to 2 µg, providing flexibility in experimental design.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast Reaction Time:\u003c\/strong\u003e Complete first-strand cDNA synthesis in as little as ~17 minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreserves RNA Template Integrity: \u003c\/strong\u003eIntrinsic helicase activity unwinds RNA structure at room temperature, making the high-temperature reaction conditions required by other RTs totally unnecessary.\u003c\/li\u003e\n\u003cli\u003eCompatible with both dye and probe-based qPCR systems\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKey Applications\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEvaluation of RNA-targeting CRISPR knockdown (Csm, PspCas13b, CasRx) — eliminates false-positive signal from guide-RNA-blocked RT\u003c\/li\u003e\n\u003cli\u003eVerification of RNAi and ASO knockdown\/knockout\u003c\/li\u003e\n\u003cli\u003eAlso supports RNA-Seq verification, alternative splice variant quantification, RNA degradation measurement, RNA editing quantification, and mutation detection\/allele discrimination\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUltraMarathonRT® First-Strand cDNA Synthesis Kit  \u003c\/strong\u003e\u003cbr\u003e\u003cem\u003eCatalog#:  R1009S (20 rxns), R1009M (50 rxns), R1009L (100 rxns)\u003c\/em\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUltraMarathonRT\u003c\/li\u003e\n\u003cli\u003e2x RT Buffer Q\u003c\/li\u003e\n\u003cli\u003eNuclease-free Water\u003c\/li\u003e\n\u003cli\u003edNTP Mix (10 mM each)\u003c\/li\u003e\n\u003cli\u003eRandom Hexamers (200 µM)\u003c\/li\u003e\n\u003cli\u003eOligo(dT)18 Primer (50 µM)\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eRNAConnect 2X qPCR Green Master Mix \u003c\/strong\u003e\u003cbr\u003e\u003cem\u003eCatalog#: Q1009S (200 rxns), Q1009M (500 rxns), Q1009L (1,000 rxns)\u003c\/em\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2x qPCR Green Dye Master Mix\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor the product brochure, click \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0872\/5613\/8010\/files\/UltraMarathonRT_RT-qPCR_CRISPR_sales_one_pager_10.7.26.pdf?v=1791569521\" rel=\"noopener\" target=\"_blank\"\u003e\u003cspan style=\"color: rgb(255, 42, 0);\"\u003e\u003cspan style=\"color: rgb(43, 0, 255);\"\u003ehere\u003c\/span\u003e\u003c\/span\u003e\u003c\/a\u003e, or for purchase orders, please contact us at sales@rnaconnect.com.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReagents Required but Not Supplied\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRNA template: 1 pg – 2 µg total cellular RNA or 1 pg – 500 ng of mRNA are recommended for each reaction.\u003c\/li\u003e\n\u003cli\u003eGene-specific RT primers (optional;
