Laminar Wash™ Centrifuge-Free Wash of Cells and Nuclei
Faster and automatible, Laminar Wash™ systems deliver higher quality data through better cell retention, better preservation of cellular physiology and viability, and improved study-to-study and operator-to-operator reproducibility.
mRNAs Optimized for Improved Stability and Performance
We now offer mRNAs that mimic fully processed mature mRNAs.
These mRNAs are stabilized with 5’ Cap 1 structure and 3’ poly(A) tail and are optimized to yield improved stability and performance.
They are modified with 5-methoxyuridine (5moU replaces U) to reduce innate immune responses. We also offer unmodified mRNAs.
Reporter gene mRNAs: ideal controls to study transfection efficiency
Genome editing mRNA: Cas9 mRNA for CRISPR Genome editing
Vaccine mRNAs: ideal as controls for immunization or vaccine studies
Lullaby Stem siRNA Transfection Reagent
Lullaby Stem siRNA Transfection Reagent is ideal for gene silencing in Stem Cells. Lullaby Stem enables siRNA and miRNA transfection of multipotent and embryonic stem cells with high efficiency and very low toxicity. Its lipid-specific formulation protects small RNA from extracellular degradation, transports them across cell membranes and efficiently releases them into stem cell cytoplasm according to the TEE-technology.
Non-viral Vaccine Carrier Adjuvants for DNA or Protein Delivery
The new VaxOZ vaccine adjuvants from OZ Bioscience are perfect for any immunization experiment.
Currently, adjuvants remain to be the most important strategy to improve the efficiency of conventional and next-generation vaccines. Genetic adjuvant is an immunological agent uses in combination with a specific antigen in order to boost the immune response. The direct consequence is to produce more antibodies and longer-lasting immunity than with the antigen alone and thus minimizing the dose of antigen needed to the vaccine. In particular, DOTAP (1,2-dioleoyl-3-trimethylammonium-propane) based cationic lipids induce maturation of dentritic cells, which then traffic to the draining lymph nodes to activate antigen-specific T cells.
In vivo grade manufactured and quality controlled, the VaxOZ adjuvants are intended for research purposes only.
CaLiVax DOTAP cationic lipid-based composition for liposome-mediated DNA or protein vaccines.
PolyVax-CPO Vaccine Adjuvant is a cationic polymer genetic adjuvant that associates with plasmid DNA to form an efficient polymer-based nanoparticle delivery system (NPD).
CNE-CPO (Cationic Nano Emulsion) Vaccine Adjuvant is an oil-in-water Cationic Nano Emulsion made of squalene droplets and cationic polymers in a continuous aqueous phase. CNE-CPO Vaccine Adjuvant is biodegradable, an important advantage over alternative oils that have been used in emulsion adjuvants.

Magnetofection™ for Enhanced Transfection Efficiency in Primary and Hard-to-Transfect Cells
Magnetic Assisted Transfection is a novel technology developed by OZ Biosciences. It has a proven high efficiency in delivering molecules into challenging cells.
Magnetic nanoparticles are associated with nucleic acids (naked or pre-complexed with a transfectionreagent or viruses) by salt-induced aggregation and electrostatic interactions.
Magnetic force drives these complexes towards the target cells, allowing a rapid concentration of the vector dose onto cells
The cellular uptake of the genetic materials is accomplished by endocytosis and pinocytosis
Nucleic acids are released in the cytoplasm by flip-flop mechanism or proton sponge effect*

Laminar Wash Sample Preparation for Single-Cell Sequencing
Single-cell genomics is rapidly growing. Nature Methods named multimodal omics the method of the year for 2019. And as more scientists use single-cell techniques, they find that sample preparation is very important to achieve high-quality data.
Single cell sequencing can suffer from poor data quality due to clumping of cells, incomplete washing of cells leaving cell-free nucleic acids, and poor retention of low numbers of cells. Washing via centrifugation causes stress on the cells in samples and can cause erroneous gene expression results.
Sample prep is extremely important in single-cell genomics, especially for single cell gene expression and immune profiling. In this area, mRNA transcripts are being barcoded and cells can experience mRNA leakage (causing increased background) or mRNA degradation (causing less signal). Unlike with flow cytometry, in single-cell sequencing it is not possible to gate out debris or groups of cells. The cell preparation must be as clean as possible and consist of single cells.
By using the Laminar Wash system scientists can see time savings and less manual manipulation.
Laminar Wash systems can wash cells without putting stress on cells that may impact gene expression, cell integrity and viability.
Nuclei Isolation Using Laminar Wash
PBMCs were lysed in bulk in tube with Lysis Buffer, quenched with Wash Buffer and centrifuged
Cells are further either washed twiced in tube by centrifuge, OR plated in Laminar Wash plate to settle for 20min, washed 7x in a Laminar Wash HT1000 System with PBS + 0.04% BSA

siRNA Off-Target Effects; Causes, Extent & Impact
siPOOLs™ are innovative, complex siRNA pools which reduce false positives & false negatives in siRNA knockdown experiments
Individual siRNAs or low complexity siRNA pools containing 3-4 siRNAs often hit multiple off-target genes and exhibit variable target gene knock-down. Short interfering RNA (siRNA) pools, siPOOLs are highly complex and defined pools of 30 siRNAs, each siRNA present at picomolar working concentrations.
dilutes the off-target signature of each siRNA, increasing on-target specificity
ensures co-operative knock-down of the target gene, producing more robust and reliable results.
