What is in Neurobasal media?

Neurobasal™ Media are basal media formulated to meet the neuronal cells special requirements. They allow for long-term maintenance of the normal phenotype and growth of neuronal cells, and maintain pure populations of neuronal cells without the need of an astrocyte feeder layer. Calcium Chloride (CaCl2) (anhyd.)

What is N2 medium?

NDiff N2 medium is a proprietary, completely defined, serum-free cell-culture supplement for the derivation, maintenance, expansion, and/or differentiation of human and mouse stem cells and tissue-derived neural stem (NS) cells.

What does having HLA-B27 positive mean?

A positive test means HLA-B27 is present. It suggests a greater-than-average risk for developing or having certain autoimmune disorders. An autoimmune disorder is a condition that occurs when the immune system mistakenly attacks and destroys healthy body tissue.

What is a HLA-B27 blood test?

An HLA-B27 test is a blood test that identifies HLA-B27 proteins. Human leukocyte antigens (HLAs) are proteins commonly found on white blood cells. These antigens help your immune system identify the differences between healthy body tissue and foreign substances that may cause infection.

What does Xeno free mean?

Our ‘Xeno-Free’ products are non-xenogeneic and animal serum-free. i.e. they do not contain material from species other than human origin. Materials that are described as being ‘Xenogenic’ are derived from a different species and therefore are not genetically or immunologically compatible.

What is Dmem made of?

DMEM is a modification of Basal Medium Eagle (BME) that contains four fold concentration of amino acids and vitamins. Additionally, the formulation also includes glycine, serine and ferric nitrate. The original formulation contains 1000mgs/L of glucose and was originally used to culture embryonic mouse cells.
