Normal Human Astrocytes (NHA) can be used to study the function of the central nervous system and how neural cells interact. Astrocytes are glial cells found in the brain and spinal cord that play a critical role in maintenance, support, and repair of nervous tissue. Cryopreserved NHA are shipped as frozen primary-derived cultures.Did you know that by using our RAFT™ 3D Cell Culture System normal human astrocytes have been successfully used in blood-brain-barrier models?Cryopreserved CloneticsTM Normal Human Astrocytes are guaranteed through 10 population doublings, express GFAP. All cells test negative for mycoplasma, bacteria, yeast, and fungi. HIV-1, hepatitis B and hepatitis C are not detected for all donors and/or cell lots. A Certificate of Analysis is provided for each cell lot purchased.
