Pep Talk
November 23rd 2023
This month from Qkine
Developing collaborations with dynamic academic labs and other companies to provide protocol support to the field is one of the most enjoyable parts of our scientific teams’ role. This month, we’re highlighting work with Joshua Thomas, Felix Buchner and Natalia Rodriguez-Muela from the superb Deutsches Zentrum für Neurodegenerative Erkrankungen (DZNE), Germany. This study compared mTESR, Stem Flex and media containing Qkine thermostable FGF-2 (Qk053) and showed enhanced colony health with the thermostable FGF2-G3-containing media.
Also…
- Qkine high purity CNTF (Qk063) is three-fold more bioactive than another major supplier, highlighting the importance of using sensitive bioassays to provide clear quantitative information to inform protocol development and save lab resources.
- Our newly launched GM-CSF (Qk076) is an important addition to our growing hematopoietic stem cell range
- We are pleased to announce a new distribution agreement in the United States with Thomas Scientific
- New customers can benefit from a 30% introductory discount for three months
Finally, as part of our commitment to constantly improving growth factor quality and availability, we will introduce a modest price increase on January 1st 2024. Learn more below, and if you would like a quote to order before Christmas, please contact customerservice@qkine.com.
Case study
Thermostable FGF2-G3 for improved homogeneity of iPSC cultures
Our thermostable and animal-free FGF2-G3 (Qk053) is highly validated and straightforward to substitute in your standard stem cell media. Read our case study in collaboration with Joshua Thomas, Felix Buchner and Natalia Rodriguez-Muela from Deutsches Zentrum für Neurodegenerative Erkrankungen (DZNE), Germany, to see how they used FGF2-G3 to reduce weekend media changes.
Technote
Three-fold higher bioactivity of Qkine animal-free CNTF
Our new product development is underpinned by our bioactivity guaranteed promise; all our proteins have equivalent bioactivity or are more bioactive than other major suppliers to ensure your results are reliable and reproducible every time. CNTF, essential for differentiation and maintenance of several neuronal, glial, and retinal cell types, is a good example where we have compared Qkine CNTF (Qk063) with CNTF from another major supplier and show the Qkine protein has a 3-fold lower EC50 in a quantitative reporter assay.
New product
Highly bioactive GM-CSF (Qk076)
GM-CSF is a cytokine that induces the development of myeloid, erythroid, and megakaryocytic cell lineages. Qkine GM-CSF is animal-free, highly pure, and has equivalent or better bioactivity than other suppliers to ensure reproducible results in your stem cell culture.
Notification
Price increase on January 1st 2024.
As part of our commitment to constantly improving growth factor quality and availability, we will introduce a modest price increase on January 1st, 2024. This increase ensures we can sustain the high level of service and innovation you expect from us whilst remaining competitively priced.
Should you have any questions or would like to request a quote ahead of the price adjustment, please do not hesitate to visit our website or contact us at customerservice@qkine.com. We are here to support your scientific journey every step of the way.
Thank you for being a valued part of the Qkine community.
