MFAP4, Recombinant, Human (Microfibril-associated Glycoprotein 4)

Microfibril-associated protein 4 (MFAP4) was initially identified as a gene commonly deleted in the contiguous Smith-Magenis syndrome (SMS) gene. MFAP4 was identified as growth factor to support expansion of hematopoietic stem cells in culture. It is involved in calcium-dependent cell adhesion and intercellular interactions. Sequence: Human MFAP4 (aa1-255) is fused at the C-terminus to a FLAG(R)-tag, expressed in HEK 293 cells. Molecular Weight: ~36kD (SDS-PAGE), Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months after receipt at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
