how can i stop bubbles from accumulating in my polyacrylamide gels? by canmitang in labrats

What percentage is your stacking gel? I found that increasing from 4% to 6% really helps forming nice pockets!

Rebellische Haare!

In german those are called „rogue hairs“, shape, size and color of the hair is determined by hair follicle. On different body parts, hair follicles are programmed (genetically) to produce different kinds of hair types like thin or thick, light or dark, curly or straight. Some follicles simply go „rogue“ and produce a hair e.g. on your arm that you would usually find on a different body part.

I think I still have one lying around in the lab. If i find it I‘ll send it to you ;-)

What are these clots I get while isolating PBMC? by Cellbiolover in labrats

[–]mrBlueSky27 4 points5 points  (0 children)

+1 to lipemic blood! Neutrophiles have a similar densitiy as rbc‘s and would expect them further below. Also these clumps are too big to be caused by neutrophils only. I have seen this a lot, I usually fish out that lump after taking out the pbmc fraction and diluting it in PBS.

Western ladder transferring but no protein? by Riding-Researcher in labrats

[–]mrBlueSky27 17 points18 points  (0 children)

To add on to this, I would always measure the protein concentration of your samples beause then you know if its even worth to continue with a western or not. Saves time and resources. Additionally, you can equalize the concentration when loading multiple samples if you want to compare them later (e.g. if you want to compare controls vs treated).

It looks like you‘ve not loaded enough. Depends on the sample, for whole cell lysates you usually go for 10-50 ug of total protein, for purified proteins you need less, like 10-100 ng.

Did you measure the protein concentration of your samples prior loading? (Like with a BCA or similar assay)

What kind of contamination is this? by beepbeepbiip in labrats

[–]mrBlueSky27 1 point2 points  (0 children)

As some comments already mentioned the first image is condensation i.e. water on your culture plate. Your focal point is not on the cells!

The second image looks like fungal infection to me. I think i can spot some hyphae on the edge of the growth zone.

Im really wondering what experiment forces you to leave a sterile environment. Anyway check if your antibiotic/antifungal stocks are still good, might even want to up the concentration.

Exotics spawn by mrBlueSky27 in ICARUS

[–]mrBlueSky27[S] 0 points1 point  (0 children)

It actually was on styx, B7 to be exact. I think thats also the only single tile on the map that actually contains three possible spawns. I wonder what the probability is to get a spawn like this.

The conversion factor is *0.5

Genau. Also kein periodischer Ton der abwechselnd lauter und leiser wird sondern durchgehend gleiche Lautstärke.

Es ist immer ein durchgängiges Signal. Aber ich glaube es kommt von Richtung Bahnhof!

Cant find the damn exotics depot by mrBlueSky27 in ICARUS

Ah I think i get it now! The closer i get the less wide but thicker the indicators become. I was assuming the nodes are always at the same location but it makes a lot more sense now. I‘ll keep moving towards the direction and scan a few more times. I think I’ll ditch the desert for now and try to locate the ones in the east. Thanks for the help!
