Scientist Solutions: International Life Science Community By Scientists For Scientists

Thanks to our sponsors who make this site possible
Pippuri' Bench [how it works]
My Bench Space is your space on Scientist Solutions, with both a private area where you can keep track of your account settings and favorite postings, and a public area where you can upload your picture, customize your profile, or start a blog

My Summary
Keeps a log of the topics you've started, the replies you've made, protocols or events you've posted, etc. Your summary will show up in your public profile.

My Blogs
You can create as many blogs as you like. They'll be viewable by anyone who looks at your profile, and they will also be indexed and listed in The Forums section of Scientist Solutions

My Lab Drawer (private)
As you browse through Scientist Solutions, you may see a topic, event, job or protocol that you'd like to store so that you can find it again easily. By clicking the "Save to My Bench Space" button next to any item on our site, you will put that item in your lab drawer for future reference.
You can also add fellow scientists to your lab drawer by clicking the "Save this scientist to My Bench Space" link next to that member's name in their posts or Bench Space profiles.

My PubMed Alerts (private)
This really cool tool allows you to set up email notifications whenever and article in your area of interest (specified by keyword is published in PubMed

Hi Sophie, what is the source of neutrophil you use in your experiment? Did you observe any clumps while handling them?

Replied to topic in Cell Culture and Tissue Culture forum   does MG132 dissolve in culture media? pls im desperate for help

Hi Annafreud, There are couple possibilities- How did you prepare MG132? While MG132 is very stable in organic solvent, it is rather unstable in aqueous condition. It has to be prepare fresh in the aqueous solution (ie. media) on the same day of experiment. The cells that you are treating M ...

Hi Annafreud, It isn't clear to me the problem that you are encountering is either the irreproducible results or the cells are dying (or not dying). Can you please elaborate?

Replied to topic in Biochemistry forum   Sequence specific pulldown of dsDNA

Hi Baconman, In theory, it should work. I guess it is just a matter of optimization, which requires patience of a saint! :-) Good luck.

Replied to topic in Cancer forum   Western blot analysis

Hi Britjade91, What is the blot corresponding to the imageJ histogram? phospho-ERK? Does the blot give you one or two bands? Depends on the source of your sample, some time you see one band, some time you see two... If you are getting two bands and both of them are your target, then I would gr ...

Hi gsitara11, Many PIs pay first year post-doc per NIH guideline. Right now it is USD 39264 per year. But the number is negotiatable- some pay more than that, some pay less than that. Living expenses really depend on which part of the country you are looking are. Even in the same state, living ex ...

Replied to topic in Protein Detection (Western blots, gels, IP) forum   Problem with SDS-PAGE

Hi kola, One possible explanation leads to such staining pattern is bacterial growth in the running buffer. Try to prepare fresh running buffer from scratch and store it in a fresh container and run a gel again. Good luck

Replied to topic in Biochemistry forum   western blotting

Hi milsey, Try to incubate your sample at 56 to 70 degree for 15 min instead of 95 to 100 degree often help with keeping membrane proteins in solution and may help with your detection. Good luck
