| E-Cadherin/Fc chimera | Reagent | Sigma-Aldrich | E-2278 | Dissolve 0.1mg of solid E-cadherin in 100ul of 1x MBS-H containing 40% glycerol to make 100x master stock (1.0mg/ml). Store it in €“20C. Make 1/100 dilution with 1x MBS-H to make 10ug/ml working solution just before you use. You need 200ul per samples of this working solution. |
| Fibronectin, 0.1% solution | Reagent | Sigma-Aldrich | F-1141 | This pre-made solution can be used as 50x stock. Make 1/50 dilution with 1x MBS-H make 20ug/ml working solution just before you use. You need 200ul per samples of this working solution.I do NOT recommend using solid Fibronectin, because it is difficult to dissolve at 0.1% concentration to make the stock solution. Although it is more expensive, this pre-made 0.1% solution is better to obtain consistent results. |

* Possible challenges/problems with using streaming video-problems may be associated with the preparing of the video, setting up, demonstrating and voice recording
* Whether or not you currently use streaming video in your class-I don't use any streaming video at this time
* Whether or not you plan on using streaming video in your hybrid class, and if so, how-I would love to use straming video for demos of skills.
* Any online sources of streaming video with which you are familiar-medscape strams vidoeos periodically which I have incorporated into my lectures.
