    HemEX™ - Type9A

    Mouse HSC expansion basal medium

    Upgrade version of HemEX™-Type9A now available.  Click Here for press release.

    Product Basics

    HemEX™ – Type9A is a basal medium specifically designed for the expansion of mouse hematopoietic stem cells (HSCs) isolated from bone marrow. Contaminants derived from albumin can trigger the differentiation of HSCs. By substituting albumin with polyvinyl alcohol (PVA), HemEX™ – Type9A can maintain HSCs in an undifferentiated state for over one month during expansion culture.

    Key Features

    Technical Information

    Maintaining the Undifferentiated State

    HemEX™ – Type9A utilizes polyvinyl alcohol instead of albumin to minimize oxidation reactions and suppress the differentiation of HSCs.

    Fig.1 Flow cytometry analysis of mouse HSCs that were cultured in HemEx®-Type9A supplemented with 10ug/mL of stem cell factor cytokines and 100ug/mL of thrombopoietin (TPO) for 7 days using U-bottom plates. Based on the characteristics of Lin – / Sca-1 + / c-Kit +, the cultured cells maintained their stemness.

    Formulation

    Based on the Wilkinson et al 2019 publication.
    **Requires the addition of cytokines.
    **Penicillin and streptomycin are not in HemEx™ but maybe add based on your needs.
