The PicoPLEX Gold Single Cell DNA-Seq Kit (PicoPLEX Gold) is designed to generate high-quality DNA libraries from single cells for sequencing on Illumina platforms. The kit is based on our patented PicoPLEX technology and is optimized for the reproducible detection of copy number variants (CNVs), single nucleotide variants (SNVs), indels, and small structural variants. The PicoPLEX Gold kit outperforms the leading Multiple Displacement Amplification (MDA) technology for SNV detection.
The PicoPLEX Gold Single Cell DNA-Seq Kit has been reconfigured from the original versions of PicoPLEX kits and does not include indexes. Compatible index kits are described below and can be purchased here.

PicoPLEX WGA (PicoPLEX) quasi-random priming technology is the international gold standard for whole genome amplification (WGA) for subsequent detection of CNVs in fixed or unfixed single cells. Initially, PicoPLEX chemistry was created for the reproducible detection of aneuploidies and CNVs. To address the need for accurate detection of SNVs, we further optimized the PicoPLEX WGA chemistry using enzymes, primers, and protocols that improve sequencing coverage, uniformity, and accuracy while increasing the resolution for CNVs, SNVs, indels, and other small structural variants while retaining reproducibility.
The enhanced chemistry named PicoPLEX Gold is a single-cell library prep kit with a simple, four-step protocol to convert fixed or unfixed single cells into NGS libraries in under three hours with minimum hands-on time.

DNA HT Dual Index kits are designed for use with ThruPLEX and PicoPLEX library preparation kits to construct libraries for multiplexed sequencing on Illumina sequencers. These kits contain indexed PCR primers carrying the Illumina Nextera® XT v2 index sequences and offer a total of 384 dual indexes for multiplexing of up to 384 samples. The indexed PCR primers are supplied pre-dispensed in four different barcoded index plates, each of which contains one-fourth of the possible dual index combinations (Cat. # R400660–R400663); or in a set of 24 individual tubes, each containing a different dual index combination (Cat. # R400664). Each dual index tube (24N) contains sufficient volume for up to two uses. Each well of a dual index plate (96N Sets A–D) contains sufficient volume for a single use.
DNA Unique Dual Index kits
DNA Unique Dual Index kits are designed for use with ThruPLEX and PicoPLEX library preparation kits to construct libraries for multiplexed sequencing on Illumina sequencers. These kits contain indexed PCR primers carrying the "IDT for Illumina UD" index sequences and offer a total of 96 dual indexes for multiplexing of up to 96 samples. The indexed PCR primers are supplied pre-dispensed in four different sets of 24 individual tubes, each of which contains one-fourth of the possible dual index combinations (Cat. Nos. R400665–R400668). Each dual index tube (24U Sets A–D) contains sufficient volume for up to two uses.
DNA Single Index kits
DNA Single Index kits are designed for use with ThruPLEX and PicoPLEX library preparation kits to construct libraries for multiplexed sequencing on Illumina sequencers. These kits contain indexed PCR primers carrying the "TruSeq LT set A" index sequences and offer a total of 12 single indexes for multiplexing of up to 12 samples. The indexed PCR primers are supplied pre-dispensed in four different sets of 12 individual tubes, each containing a different index sequence (Cat. Nos. R400695 and R400697). Each single index tube (12S Sets A–B) contains sufficient volume for up to eight uses.

基因组文库是一个比较笼统的概念。这个文库可以指某种真核生物的基因组，也可以指某种原核生物的基因组。实质是将某种生物的全部遗传信息贮存在一个受体菌群体中，做为目的基因的来源。
cDNA文库显然比基因组DNA文库小得多，能够比较容易从中筛选克隆得到细胞特异表达的基因。但对真核细胞来说，从基因组DNA文库获得的基因与从cDNA文库获得的不同，基因组DNA文库所含的是带有内含子和外显子的基因组基因，而从cDNA文库中获得的是已经过剪接、去除了内含子的cDNA。
真核生物基因组DNA十分庞大,其复杂程度是蛋白质和mRNA的100倍左右,而且含有大量的重复序列. 采用电泳分离和杂交的方法,都难以直接分离到目的基因.这是从染色体DNA为出发材料直接克隆目的基因的一个主要困难。
高等生物一般具有10^5种左右不同的基因,但在一定时间阶段的单个细胞或个体中,都仅有15%左右的基因得以表达,产生约15000种不同的mRNA分子.可见,由mRNA出发的cDNA克隆,其复杂程度要比直接从基因组克隆简单得多。
cDNA文库在研究具体某类特定细胞中基因组的表达状态及表达基因的功能鉴定方便具有特殊的优势，从而使它在个体发育、细胞分化、细胞周期调控、细胞衰老和死亡调控等生命现象的研究中具有更为广泛的应用价值，是研究工作中最常使用到的基因文库。
