Thank you Rabeah!

Vahid Razban

Hi,

You can also search Geltrex in google and also Geltrex vs Matrigel.

Geltrex is an alternative to Matrigel.

Best

Dear Vahid, thank you for your answer. It was my second choice and I already asked for Geltrex yet, it is also not avaliable…at least in Japan.

Elizaveta Prosekina Thank you I will also check that!

Andrew Mearns Spragg

Hi Zeyep,

I noticed your comment about matrigel alternatives, have you considered Type-0 marine collagen from Jellagen? A non-mammalian Matrigel alternative.

We have comparative data we would be happy to share. We have stock on the shelf and would love you to try it, please DM one of our product specialists, [email protected] you want to know more.

Kind regards,

Andrew

AAndrew Mearns Spragg hey Andrew thank you for your answer. The previous day the Jellagen company got in touch with me via Twitter and I checked the product. Unfortunately there is no study related with angiogenesis however I will be thinking of using it in the next months may be.

Zeynep Bal Thank you for the reply, hope all is well? That is great that you will be thinking of us, I am keen to arrange a call with the Head of Chemistry as he can go through any technical information about our products. Please get in touch with Shonte (product specialists as she can answer any questions you have). We have a few whitepapers coming out soon which we can share with you.

Andrew Mearns Spragg Thank you for the detailed information!
