The new SMARTer Mouse BCR IgG H/K/L Profiling Kit is the latest addition to our immune profiling portfolio. This kit pairs 5’ RACE with our SMART NGS technology to provide a sensitive, accurate, and optimized approach to B-cell receptor (BCR) profiling. The 5'-RACE method reduces variability typically found with multiplexing approaches and allows for priming from the constant region of BCR heavy or light chains. These benefits are combined with gene-specific amplification to capture complete V(D)J variable regions of BCR transcripts. This kit:
Accommodates inputs of 10 ng–3 µg of total RNA from spleen, lymph node, PBMCs, and hybridomas
Provides specific, accurate amplification of BCR heavy and light chains
Includes an optimized PCR pooling strategy for highly sensitive detection of different chains from the same sample
Enables flexibility in pooling strategies for different experimental requirements regarding alignment and identification of primary chain sequences

Isolates exosomes in under 30 minutes without ultracentrifugation—from cell culture supernatant collection through elution
Provides all the necessary columns and buffers—preclearing columns to remove cellular debris, isolation columns for exosome binding, and optimized buffers for the isolation
Yields up to 2 x 1011 of purified exosomes per column, depending on cell type and cell culture conditions
We are pleased to announce the release of the Guide-it Long ssDNA Production System, designed to produce a long single-stranded DNA (ssDNA) oligo of up to 5 kb in length, for use as a repair template in knockin experiments using CRISPR/Cas9 or other genome editing tools. One of the major challenges of knockin experiments is the production and delivery of the repair template along with the Cas9-sgRNA ribonucleoprotein complex. Although ssDNA repair templates have been shown to be more effective for gene editing than double-stranded DNA, their use is limited due to the difficulty of producing long templates or needing to use adeno-associated virus (AAV) for delivery. The Guide-it Long ssDNA Production System provides a fast and simple in vitro method for generating long ssDNA donor templates, which do not randomly integrate into the genome, are less toxic to cells, and do not require AAV production, resulting in improved gene editing efficiency.
ssDNA does not randomly integrate into the genome, unlike dsDNA
ssDNA does not express unless properly integrated into the genome, making identification of correctly edited cells more accurate when delivering expression cassettes
ssDNA causes significantly less cytotoxicity in edited cells when compared with dsDNA
Looking for a complete system to create CRISPR/Cas9-edited human iPS cell lines? Our carefully designed, “start-to-finish” editing and culture systems directly deliver Cas9/sgRNA ribonucleoproteins, providing a fast turnaround for gene editing while minimizing off-target effects compared to vector-based approaches.
Furthermore, our complete systems circumvent a major bottleneck in the hiPSC editing process: survival and expansion of edited single clones. Traditionally, the establishment of a clonal population from hiPS cells grown as colonies results in cell death or premature differentiation. However, Cellartis’ kits contain a defined culture system that promotes monolayer growth, overcoming the challenges of colony-based culture by allowing efficient single-cell passaging and promoting expansion of highly pluripotent, edited hiPSCs.
Efficient gene editing in hiPSCs—use electroporation or gesicles to deliver Cas9 protein and sgRNA with no genomic integration and reduced off-target effects
Maintenance of pluripotency and stable karyotype from start to finish—hiPSCs maintain high levels (>90%) of pluripotency markers and a normal, stable karyotype throughout editing, single-cell cloning, and expansion
Flexibility to perform gene editing experiments your way—choose from two different all-in-one editing and single-cell-cloning solutions, or use the culture media kit to perform efficient single-cell cloning following your own editing experiments
We are pleased to announce the release of the SMARTer Stranded Total RNA-Seq Kit v2 - Pico Input Mammalian (Pico v2), an updated version of our industry-leading solution for analysis of challenging samples. The Pico v2 kit is designed to generate Illumina-ready sequencing libraries from 250 pg–10 ng of high-quality, partially degraded, or low-quality mammalian total RNA, including RNA obtained from FFPE samples. Like its predecessor, the Pico v2 kit retains strand-of-origin information and employs a proprietary technology for the removal of ribosomal cDNA following reverse transcription and PCR amplification. Updates included in the Pico v2 kit provide improved sequencing performance, resulting in higher percentages of clusters passing filter (%PF) without the addition of PhiX, thereby reducing sequencing costs. The Pico v2 kit also includes a new buffer formulation that improves sample handling during library purification.
Generates high-quality Illumina-ready sequencing libraries from 250 pg–10 ng mammalian total RNA inputs of any quality, including RNA obtained from FFPE or LCM samples
Provides improved performance and sequencing metrics on all Illumina platforms, including higher %PF, more transcripts identified, and lower duplicate rates
User-friendly workflow can be completed in ~6 hours
Cellartis human embryonic stem (ES) cell line kits contain human ES cells that have been ethically derived under feeder-free conditions, then banked and characterized according to the highest industry standards. The human ES cells are adapted to the Cellartis DEF-CS culture system, an easy-to-use, complete culture system for pluripotent cell expansion in a defined, feeder-free environment that maintains high levels of pluripotency. The reproducible nature of the DEF-CS system coupled with the stable high growth rate of these stem cell lines is ideal for small- or large-scale expansion, as well as any major downstream applications.
