Sygnis TruePrime Single-Cell WGA Kit V2
Sygnis has launched the TruePrime Single-Cell WGA Kit V2 for whole-genome amplification. The kit is based on the company's TruePrime DNA amplification technology, which uses a combination of proteins to efficiently amplify the smallest amounts of DNA. Features include a complete absence of common artifacts linked to the use of oligonucleotides; reduced amplification bias in genome coverage compared to methods using random synthetic primers; and the inclusion of human genomic DNA as an internal positive control. In addition, the kit provides new lysis conditions that allow WGA from a broader range of cell types, the company said.
BioVendor Instruments MALDI Colonyst
BioVendor Instruments has released the latest generation of MALDI Colonyst, an intelligent robot for colony picking and complete MALDI target preparation. MALDI Colonyst fully automates sample preparation for microbial identification using MALDI-TOF mass spectrometry, either with Bruker's MALDI Biotyper or BioMérieux's VITEK-MS. In addition, by using a newly developed process called wet deposition, the platform has shown a 10 to 15 percent improvement in MALDI identification scores for more difficult microbes, the company said.
CSI Laboratories PD-L1 Expression Assay
CSI Laboratories, a private national reference laboratory specializing in cancer diagnostics, has launched a PD-L1 (programmed death-ligand 1) immunohistochemical protein expression assay, which can be used to potentially predict a patient's response to several commercially available PD-1/PD-L1 inhibitor therapies. More specifically, the assay provides a specimen's PD-L1 tumor cell reactivity score, which can be used to identify patients who are more likely to respond to certain PD-1/PD-L1 inhibitor therapies.
