Stampwell

A family of 6 stamps designed to make culture and imaging 
of 
zebrafish embryos, medaka and organoids 
as easy as cost-effective

Overview

 

Stampwell stamps imprint arrays of wells in hydrogels in just one time. Nothing more to do than load your samples into the wells and image. The Stampwell shapes have been optimized for the imaging of spheroids/organoids as well as fish embryos or larvae up to 20 dpf.


A technology originally designed by​  Gaëlle Recher  for spheroids & organoids
Powered by the Mount(n) technology (UniverSlide) published in  Scientific Reports
Optimized by Idylle thanks to the Test Program feedback for zebrafish and medaka

Those little extras that make all the difference:

 
 For stamps with more than 10 wells, alphanumeric markers make it possible to quickly identify 1 particular sample. 
 When you move your dish from the incubator to the microscope, the samples remain quietly in their wells (except the Stampwell made for aggregation) 
 Image your biological samples growing for several weeks in the same dish.

Feedback from users

 

I successfully managed to use Stampwell with Collagen-1.

 Matthieu Opitz • Alveole, France

I use the Stampwell V-shape to track the explants development and the embryoids formation from stem cell aggregates in zebrafish, and it makes my work much easier!

 Queralt Tolosa • Centre for Genomic Regulation, Spain

I used a Stampwell to ensure that my zebrafish embryos were positioned correctly under the microscope for spatial and temporal experiments. I am pleased with my Stampwell because it saves me time and provides precision!

 Shai Eyal • UCSD, USA

Stampwell has proven to be a very easy to use mounting medium for confocal imaging of fixed and immunostained zebrafish embryos.​

Features

Cross-dishes

Compatible with most 35 mm dishes and 6-well plates

Reusable

Use your stamp dozens of times

Safe for transport

Keep samples at the bottom of the wells, even when a dish is upside down

Long-term imaging over weeks

Samples lay on the bottom of the well. They can freely grow within it to image multiple times.

Alpha-numerical markers* 

create an organized network of samples to identify the samples for a posteriori experiments
* for > 10 wells Stampwells 

Protocol

Global protocol 

 

Pour liquid agarose

Place the stamp

Reticulate the hydrogel

Remove the stamp

To image, just load your samples and image, sequence, transport at will.

To aggregate, seed your cells & let them aggregate.

Story

" The Stampwell family of products is born from a technology that I designed, called Mount(n). It is the result of my expertise in imaging a wide range of 3D thick samples. I navigated through many communities (gathered around a biological model), and each time I learnt new tricks to mount samples for microscopy experiments. The Mount(n) technology consists in imprinting an array of wells into a hydrogel (typically agarose), each well receiving a 3D sample (embryos of any species, organoids, tissue biopsies...). The design of the wells pr events the object from moving when the plate or dish is moved, does not apply any mechanical constraints to the sample, and paradoxically also enables the sample to keep growing inside. In a single dish, tens of samples can be imaged with any microscope, for as long as necessary. "

New projects at Idylle
" Together, we turned the Mount(n) technology into a family of research products. First, we have evolved the shape, the color and the material to offer an ergonomic grip and functionalities that meet the usage characteristics of most applications. Then, as we were about to start the production, the first testers found out that the stamp did not fit in all their dishes. Within a few days, together with Gaëlle and our design office, we redesigned a shape and in April 2021, the Test Program for the first Stampwell  models, 2 V-shapes and Embryo 1, was released
But the story does not end up here! More and more researchers asked us to customize a stamp to image zebrafish and medaka embryos or larvae. So in addition to the Embyo 1, at Idylle we decided to add 3 new models that would facilite imaging them up to 20 dpf.
The rest of the story remains to be written with you!"
