Q:

Could you please let me know the full sequence, including tags, of CSB-EP013323HU and CSB-YP013323HU MAGE A1?
I am wondering why, despite being the same protein, I run at different MWs.

A:
Thanks for your inquiry. Our replies are as below.
1. CSB-EP013323HU N-terminal 10xHis-tagged MW of the Tag: 5.5 KDa Tag Sequence:

MKETAAAKFERQHMDSPDLGTLVPRGSMADIGSEFHHHHHHHHHHLVPRGSRT


2. CSB-YP013323HU N-terminal 6xHis-tagged MW of the Tag: 2 KDa Tag Sequence:

EAEAYVHHHHHHEFRT


3. The MW of the target protein is 34.3 KDa. The target protein sequence is as follows.

MSLEQRSLHCKPEEALEAQQEALGLVCVQAATSSSSPLVLGTLEEVPTAGSTDPPQSPQGASAFPTTINFTRQRQPSEGSSSREEEGPSTSCILESLFRAVITKKVADLVGFLLLKYRAREPVTKAEMLESVIKNYKHCFPEIFGKASESLQLVFGIDVKEADPTGHSYVLVTCLGLSYDGLLGDNQIMPKTGFLIIVLVMIAMEGGHAPEEEIWEELSVMEVYDGREHSAYGEPRKLLTQDLVQEKYLEYRQVPDSDPARYEFLWGPRALAETSYVKVLEYVIKVSARVRFFFPSLREAALREEEEGV


The MW of fusion protein CSB-EP013323HU: 5.5KD+34.3KD= 39.8 KD
The MW of fusion protein CSB-YP013323HU: 2KD+34.3KD= 36.3KD
The vectors used for EP and YP are different, and the tag sequences contain part of the vector sequence, so their MW are different.
