NEW PRODUCT HIGHLIGHT

IFN-gamma (interferon-gamma) is a cytokine crucial for immune responses, produced by T cells and natural killer cells. It activates macrophages, enhances antigen presentation, and plays a key role in inflammation.

Qkine has optimised the IFN-gamma manufacture process to produce a highly bioactive protein with excellent lot-to-lot consistency for enhanced experimental reproducibility.

Bioactivity was determined by a cytotoxicity assay using HT-29 cells. Cells were treated in duplicate with a serial dilution of Qkine IFN-gamma (Qk117, green) for 88.5 hours. Cell viability was measured using the CellTiter 96 AQueous Cell Proliferation Assay (Promega). Assay was performed by SBH Sciences using their standard (black) for comparison. Data from Qk117 lot #204692.

DISCOVERY KITS

For current hiPSC media comparison with B8 media to see if your cells can be maintained as efficiently while giving you the weekends off.

Also see application note: Weekend-free human induced pluripotent stem cell culture

For rapid testing of Beefy-9 against current serum-free bovine stem cell maintenance media to evaluate whether your bovine satellite cells can be expanded more efficiently.

Also explore our high quality food grade growth factors

For rapid optimization of your media to become entirely serum-free. This kit contains 7 growth factors commonly used in a variety of serum-free media. Use it to optimize media for your cells to fully define your media.

For rapid testing of FGF-2 with thermostable FGF-2  protein, to determine whether the short half-life of FGF-2 is impacting cell fate.

PRODUCT SPOTLIGHTS

Mouse LIF (murine leukemia inhibitory factor) protein maintains the pluripotency and self-renewal of mouse embryonic and induced pluripotent stem cells.

Is there a difference between recombinant mouse LIF protein and ESGRO?

Stem Cell Factor (SCF) is a critical factor in the maintenance and expansion of hematopoietic stem cells (HSCs) in the bone marrow microenvironment. Key myeloid progenitor differentiation factor for a variety of myeloid cells such as megakaryocytes, basophils, neutrophils, and monocytes, stem cell factor is also a primary growth and activation factor for mast cells and eosinophils.

Recombinant mouse SCF coming soon

Qkine stem cell factor (SCF) is as biologically active as a comparable alternative supplier protein
