About

BASIC LEAF CUTTING TOOL

The 3CR Bio Basic Leaf Cutting Tool is a lightweight, easy-to-use, low-cost punch designed for precise sampling of thin or soft materials, ideal for fieldwork. This tool is expertly designed to core, punch, and retrieve samples from thin or soft source materials such as leaves. The tool comprises a convenient, hollow plastic pen-style holder, mounted with a durable stainless steel cutting tip at one end. It features an internal push-button-operated plunger for safe and efficient sample disc ejection. The tool produces a precise ¼ inch diameter disc, making it ideal for detailed sampling tasks. For best results, clean the cutting tip between each sample extraction by coring blank filter paper or rinsing with water or ethanol. This low-cost leaf punch is lightweight, easy to use, and perfect for fieldwork.

ADVANCED LEAF CUTTING TOOL

The 3CR Bio Advanced Leaf Cutting Tool is designed to streamline and enhance your sampling process. This high-precision leaf tissue punch produces a single ¼ inch diameter disc effortlessly. It features a unique mechanism that securely holds a standard snap-top or screw-top 2 mL storage tube in a fixed position, allowing the sample to be received without any need for touching or manipulation. Ideal for fieldwork, this advanced leaf punch significantly reduces effort and time when performing multiple samplings, ensuring accuracy and efficiency in every use.

The PCR-free NGS DNA Library Prep Kit was developed for construction of DNA libraries for next generation sequencing (illumina platform). The kit adds 3′-dT-tailed library adapters to both ends of DNA fragments efficiently. The kit uses double strand DNA fragments (blunt and/or sticky) as input DNA for NGS library construction, and is compatible with DNA fragments generated from both enzymatic methods (BioDynami DNA fragmentation enzymes etc.) and physical methods (sonication, nebulization etc.).

PCR-Free NGS DNA Library Prep Kit Workflow

PCR amplification is a standard step for library preparation of Next-Generation Sequencing. The PCR is used to amplify fully ligated DNA fragments and to add index information to the libraries. The indexing is for the pooling of the library samples in an effort to reduce the sequencing cost.

However, PCR introduces uneven amplification of DNA in some DNA regions with extreme GC-contents and secondary structures. This bias can cause very low sequencing coverage in such regions. DNA sequencing in these regions is still a huge challenge.

PCR-free library prep can reduce library bias and minimize sequencing gaps. The sequencing data from PCR-free library samples have even genomic coverage with few gaps and better depth in GC-rich regions. Our PCR-free NGS kit offers optimal coverage in the regions that are traditionally difficult, such as high-GC content regions, low-GC content regions, and repetitive sequence regions.

Two index types are available for the kit:

Non-index: Libraries do not have index.

Index: Each library contains one i5 index and one i7 index.  Library multiplexing up to 96 samples is possible. List of indexes can be downloaded Here.

Kit advantages:

• • • Total time: 1 hr
    • Hands-on time: 5 min
    • Easy procedure: Ready-to-use master mix & Less reaction components
    • Input DNA amount from 100 ng to 1 ug
