Merck Life Sciences Products & Reviews

S-Pak ® sterile, individually packed, gridded membrane filters are made from mixed esters of cellulose and have been optimized for MF method microbiological analysis of water or other liquids.

GranuCult™ is our new brand name for our existing granulated dehydrated culture media which apply to new EN ISO 11133:2014 and various other ISO standards and FDA-BAM / USDA-FSIS methods for testing of food and water samples. All these media are currently being updated to be fully compliant to the latest version of these standards and regulations with respect to composition and quality control and will be available shortly.

Trusted TRC (The RNAi Consortium) content with shRNA targting 20,000+ human or 21,000+ mouse genes including TRC 1.5 and 2.0 (unique and validated) add-ons which are exclusive to Sigma

We have applied CompoZr Zinc Finger Nuclease technology to create an unparalleled range of genetically modified mammalian cell lines for use in areas, such as target validation, drug discovery and drug development.

CompoZr ® ZFN (zinc finger nuclease) technology was used to insert the sequence for fluorescent proteins adjacent to endogenous genes to create reporter cell lines for compound screening

A pre-engineered cell line with integrated genetic elements for simple payload exchange of your specific promoter and gene of interest. The landing pad construct is targeted to the AAVS1 safe harbor locus with a fluorescent marker for downstream screening.

The human CRISPR ′Brunello′ pooled library is designed using optimized metrics, as published by, Doench et al. Nat Biotechnol. (2016) and described further in Sanson, K.R., et al. Nat Commun (2018)

The Human Whole Genome Toronto KnockOut Library v3 (TKOv3) is optimized for editing efficiency using empirical data described in the findings by the Moffat lab.

The human, paired guide Poison (pgPoison) library targets 3` splice sites with paired guide RNAs for alternative exon removal (pgRNAs), induce skipping of "poison" cassette exons and corresponding upstream constitutive exons in ultraconserved regions.

The mouse CRISPR "Brie" lentiviral pooled libraries are designed using optimized metrics, as published by Sanson, K.R., et al. Nat Commun 9, 5416 (2018), which combine improved on-target activity predictions (Rule Set 2) with an off-target score, the Cutting Frequency Determination (CFD)

The Human CRISPR inhibition (CRISPRi) library (Dolcetto) is a single compact library that inhibits over 18,000 human genes and is used for genome-wide inhibition screening using a KRAB-dCas9 effector.

The 10x Compatible Human CRISPRi Kinase Phosphatase Drug Targets Kit (Druggable Genome) contains one sub-pool of the top two ranked sgRNAs per gene for increased sensitivity and includes non-targeting controls built-in.

The Human CRISPR activation library (Calabrese) activates over 18,000 human genes and is used for genome-wide activation screening. The library is designed to be compact and efficient to maximize screening efficiency and performance, as published by Sanson, K.R., et al. Nat Commun 9, 5416 (2018).

The mouse CRISPR activation library (Caprano) activates over 22,000 mouse genes and is used for genome-wide activation screening.

Easily identify hits from pooled shrna screens

Design gRNA or search pre-designed guides

The control kit includes validated positive control targeting RAB1A and non-targeting control for assay set-up and a UCOE KRAB-dCas9 for consistent effector expression across a wide variety of cell lines. The kit is ideal for setting up the screen assay and optimization before using the CRISPRi library pools.

The 10X CRISPRi Feature Barcode Optimization kit is ideally suited for setting up the screen assay and if desired capture sequence optimization before using the Custom 10x Compatible CRISPRi library pools.

The MISSION pLKO.1-puro Control Vector is a lentivirus plasmid vector. The vector does not contain an shRNA insert and is useful as a negative control in experiments using the MISSION shRNA library clones.
