siRNA is easy to transfect because of very small bp. Therefore, for siRNA transfection, lipofectamine commonly used. Polypus is preferred for plasmid transfection and for the cell lines those are very hard to transfect.

Thank you for explaining, it is so clear, I have question: when you loading the sample to western blot, did you loading it to times? Like why there are two bands in the gel??
@xgeneproteinx2889
@xgeneproteinx2889 Ай бұрын
Those two bands are for two different interacting proteins, X And Y. Loading sample once, But after respective Primary And secondary incubation against X and Y, two different bands can be detected.

How to Avoid RBC contamination in pellet? We use fresh samples for pbmc isolation. But still we get RBC mixed with cells in pellet We will use 15 ml both falcon and sepmate tube. Centrifuge 1st step we do with breaks
@xgeneproteinx2889
@xgeneproteinx2889 2 ай бұрын
You can use RBC lysis buffer to eliminate RBC. If you don't need to use PBMC instantly after isolation, Then you can keep the pbmc in the incubator (with proper PBMC culture protocol). After 24/48 h. RBC would disappear as they don't have nuclei so, they don't divide.

I tried that method after adding RBC Lysis buffer that cell count is going v less. Like with adding lysis 11.4 mil cells, after adding 7.5 mil ) Our main focus is to get good quality of cells without RBC ....... Plz clarify this: In 15 ml sepmate will add 4.5 Histopaque, 4+4 ml ( blood+ PBS) Is it high. I'm thinking that after adding all these it will go till 14.5 ml. Is it the reason for the RBC Contamination? Can I use blood mix less volume
@xgeneproteinx2889
@xgeneproteinx2889 2 ай бұрын
1. Centrifuge speed and time can be increased. 2. Fresh blood Should use for pbmc isolation. 3. Ficol paque and diluted blood ratio Should be 1:3. Follow proper Protocol to avoid RBC contamination. RBC contamination may cause due to mistakes during the isolation process.

Hi, on western blot visually 5 and 10 ug protein band is more intense compared to control but after normalization on the graph it shows control is higher amount compared to two other bands, why?
@xgeneproteinx2889
@xgeneproteinx2889 5 ай бұрын
Normalization value not only depends on intensity of the protein bands of test group. It also depends on intensity of the loading control. If you notice, you can see intensity of GAPDH (loading control) of corresponding control group is very low. This is why normalization value is less in the control group.

Affinity depends on many factors. That need to be optimized in the lab. Affinity also depends on format of the scFv. Here, I mentioned Two different formats, but also many other varities available as well. We found that 'Heavy chain abundant' has higher affinity over 'Light chain abundant'.

Your explanation is mostly correct, expect for the OD being related to the protein expression. In that example you explained is a way to measure the amount of bacteria in the medium. We only add the IPTG when the OD is high (=lots of bacteria are there, around OD=7) and in your examplary images they will keep multiplying during the protein expression to an OD of 1. Also, your images are really small and the stuff you wrote in the red letter (6:00, f.e.) is not easy not read.

1. Usually, methylation of DNA occurs in the bacteria to recognise their own DNA. When the viral DNA attack bacteria, restriction enzymes of bacteria digest Foreign DNA. Source of all plasmid DNA is bacteria. 2. Some enzymes present in the bacteria, associated with initiation of methylation process.

I have a question. In the case of antigen in the sample where you first added the antibody and it dried up, How do you achieve a control for that. Because since the antibody is loaded on to the membrane first. Won’t it bind the secondary antibody regardless of the binding to antigen. Also what’s the ratio of background when done ??

Better to add antigen first to get antigen specific binding. For the control, don't add antigen, rest of the other steps are same, so you won't get any specific blot. Here, blocking step need to be done same as western blot, so won't get background noise.
