Q:

Has CSB-YP355623MO been tested in cell culture?

A:
Thanks for your inquiry.
We haven't tested this protein in cell culture.
Q:

I have some problems in the development of the immunoassay to detect mouse insulin. Our antibodies are produced against recombinant human insulin, but they also react with mouse insulin (affinity tested). However, once I perform the immunoassay I could not see any specific signal, all signal is like background noise. I¡¯m not sure if either insulin or one of the antibodies is not working. However, I have some questions regarding recombinant mouse insulin that I hope you could answer,
Insulin purity was assessed by SDS-PAGE, addressing 85 % of purity, I don¡¯t understand why stained gel only shows one single band, theoretically there are other proteins/peptides, which could show more other bands in SDS-PAGE, right? . In this sense, if insulin expected band should be at 13 kDa (in you datasheet), why stained gel shows a single band at 21 kDa. I guess that this insulin is suitable as a standard/calibrator for immunoassays development, right? (Of course, always depending on the antibodies used).

A:
Thanks for your inquiry.
1.Our QC standard is over 85%,you can see from the COA that the purity is 90%, the MW in theory is 13kDa, the observed MW is 21kDa. The reason is because the yeast recombinant expression have extra galactosylated modification (mainly N-type high mannose modification). We have write the reason of the difference on the COA.
2.It can be used as the Elisa standard, but need a correct matched antibody,
① species of origin, the protein mouse and human sequence similarity is 81% is not very high, we are not 100% confirm it can be used cross-reaction
②The source of the immunogen is also important, the immunogen and the detection of the protein is best from the same expression system, we have encountered several times, that different systems expressed protein and antibody binding reaction is not the same.
We also have the antibody of human species (CSB-PA3589A0Rb), and have CSB-YP355623MO with the same batch in stock, while the E.coil system expression (CSB-EP355623MO) also have in stock. We are preparing do the WB test, we will send you the results once we get it.

Target Background

Function
Insulin decreases blood glucose concentration. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver.
