Is free cytosolic GFP fluorescence excluded or reduced in the endomembrane system (ER, Golgi, lysosomes)? Why or why not?

As soluble, untagged GFP is not membrane bound and doesn't contain targeting or signal sequences, one might expect it to be synthesized by free ribosomes and not bound ribosomes. That would mean...

How many base pairs mismatches should i consider to design a specific primer? my templates have 1-2base pairs mismatch only when i aligned them?

i need to design a specific primer for each of my samples. but my samples, when i aligned them, they only have 1-2 bp mismatches, barely 3

Can you recommend a fluorescent ELISA agent?

Using a fluorophore rather than a chromophore for ELISA detection seems like an obvious solution to increasing ELISA sensitivity, but I'm struggling to find work done in this area. Can anyone...

Are plasma protein free cysteines truly free?

free as in unreacted sulfydryls, not free as in speech, nor free as in beer :) I am working with an 80 kDa plasma protein with 5 cysteines, 2 of which are in a disulfide bridge. There are a lot...

Why does blocking with my immunogenic peptide cause nuclear fluorescence in ICC?

Hi all, I am validating a polyclonal antibody raised against human ANT4, through WB and ICC. In most of my controls, the antibody shows very little off-target binding, but when I pre-incubate the...

Have someone successfully used the ER alpha (Santa Cruz sc-8002) antibody in immunostaining ?

Santa Cruz now recommends this new antibody (F-10) but I can't find a publication using this reference. I'm working on human et non human primate hypothalamus and so far, it doesn't work. Is...

Is it possible for two human neuronal cell lines to have different gene sequence for the same protein?

I am looking at the ATP1A2 (Sodium/Potassium ATPase alpha subunit 2) in two human neuronal cell lines. Expression levels of this protein seems to be almost equal when detected by one antibody....

Is CD44 degraded in lysosome together with hyaluronan after CD44 mediated endocytosis of hyaluronic acid?

Also when RHAMM binds hyaluronic acid, they get internalized, will RHAMM also be degraded? Or both CD44 and RHAMM will be transferred back to the cell membrane? Asking for breast cancer cell line...

Do you need the CMV enhancer before the CMV promotor for a proper function of CMV on the gene that follows?

I'm a student and I have to produce a cell line with a knockin for the NRF2 gene with GFP. I have to put a promotor in front of the GFP because the gene will be too far away from the promotor of...

How does an antibody have full intact antibody + half antibody?

Hello, I was just wondering how does a antibody have full intact antibody + half antibody? Is it because of the drug conjugation?
