pourcentage du gel utilisé pour HERC2 en Western Blot? protocole transfert protéines de haut poids moléculaire? |
|||||||||
ANSWER: |
Le laboratoire vient de m'informer que le gel utilisé avec l'anti-HERC2 ab85832 en western blot est : 3-8% Nupage Tris-Acetate Mini gels, la membrane utilisée est de type nitrocellulose. J'espère que ces informations, ainsi que le protocole de transfert que je vous ai envoyé précédement vous aideront à optimiser les résultats. J'espère que ces informations vous seront utiles. N'hésitez pas à nous contacter de nouveau si vous avez d'autres questions. |

protocole transfert protéines de haut poids moléculaire? |
|||||||||
ANSWER: |
Veuillez trouver ci-dessous le protocole (en anglais)que nous recommandons pour le transfert de protéines de haut poids moléculaire en western blot : -We wouldsuggest to optimize the transfer conditions by increasing the transfer time to 18 or 24 hours (in some examples, for big proteins, the transfer is done for 48 hours) - A transfer at 20-30V for a long period of time is fine but it has been shown that a "boost" at 70-80V for 1 hour at the end of the transfer can be of significant improvement. -We recommendthe use ofmore SDS in the transfer buffer, up to 0.05%,as well asthe useof lessmethanol(10%). The reason is that methanol washes out the SDS from the protein. |
