Description
iMatrix-511 is a culture medium that can be used for various types of cells, and enables feeder-free culture of pluripotent stem cells (ES / iPS cells) and single-cell passage. This product "Easy iMatrix-511" can be coated on the culture vessel as it is without dilution.
The lineup includes Easy iMatrix-511 derived from CHO-S cells and Easy iMatrix-511 silk derived from silk moth cocoons.
* Recombinant Human Serum Albumin is added to stabilize iMatrix-511 and enhance its activity.
Background of Laminin and Laminin fragment
Laminin is one of the extra cellular matrix (ECM)s located in the basement membrane of animals, and play an important role for cell adhesion and proliferation.Laminin is composed of three parts ; alpha, beta, and gamma - chain and 15 types of laminin is already known. Among them, Laminin composed by Alpha5-chain, Beta1-chain, and Gamma1-chain, is called "Laminin-511".
Laminin-511 is recognized by alpha6beta1 integrin. Cell adhision, extension and proliferation is caused by many cell signalings through intergrin.Laminin-511 E8 is the fragment of Laminin-511 obtained by enzyme digestion. Although this is fragment, it has binding ability to alpha6beta1 integrin.
Features
- Ready to use
- Works in various cells - especially good for iPS / ES cells
- Reduce the risk of contamination by xeno-components in your culture system.
- High cell viability and proliferation rate.
Note: This product contains recombinant human serum albumin for stabilization and improvement of activity.
Advantage of using Laminin-511E8 fragment in ES/iPS cell culture
With conventional culture methods, cells die if ES/iPS cells are dispersed into single cells. Therefore, maintaining cell colony is necessary to a certain extent when passaging.
Using Laminin-511 E8 fragment as cell culture substrate enables to maintain and culture even a single ES/iPS.
- The period of time required for learning cell culture methods is reduced.
- The extension efficiency of cell culture is drastically enhanced.
Procedure
In the case of 6 well culture plate ... (9.6 cm2/well)
- Add 1.5 mL / well of Easy iMatrix-511 to the plate.
- Incubate the plate at 37℃ for a hour at RT or 4℃ for overnight.
- After (2), discard solution and start culture shortly. (DO NOT DRY!)
Caution: For iPS cells, recommended cell density is 2 - 3 x 103 cells/cm2. However, culture condition must be optimized.
