ReNcell Neural Stem Cell Freezing Medium is qualified for use with ReNcell immortalized human neural progenitor cell lines, CX and VM cultured in serum-free conditions with ReNcell NSC Maintenance Medium. The optimized formulation allows for consistent cryopreservation and high viability upon thawing and plating.

This unique formulation of cell culture freezing media is for cryopreservation of a broad spectrum of mammalian cells (see viability data)and is ES cell qualified. Freezing Media contain 10% of the active cryopreservation ingredient (either DMSO or Glycerol). The remaining 90% is a proprietary mixture of Calf and Fetal Bovine Serum. The reagents used in these products are certified to be virus and mycoplasma free. The sera ut…

Pure recombinant high-fidelity DNA polymerase from Thermococcus kodakaraensis KOD1KOD HiFi DNA Polymerase* is a recombinant form of Thermococcus kodakaraensis KOD1 DNA polymerase. KOD HiFi is a high fidelity thermostable polymerase that amplifies target DNA up to 6 kbp in length with superior accuracy and yield. The enzyme’s 3′→5′ exonuclease-dependent proofreading activity results in a lower PCR mutation frequency than any ot…

High-performance enzyme blend for long and accurate PCRKOD XL DNA Polymerase* is an optimized blend of KOD HiFi DNA Polymerase and a mutant form of KOD HiFi that is deficient in 3′→5′ exonuclease activity. This enzyme mixture is designed for reliable amplification of long, complex targets with robust yield and high accuracy. It can also be used for incorporation of dITP, dUTP and derivatized dNTPs in PCR amplicons. KOD XL DNA…
