Тем более, тот же этажный контроллер RN-FC5, позволяет использовать обычные трубки координатных домофонов в цифровых системах.Координатные домофонные системы более широко представлены на Российском рынке домофонов.Но и здесь ситуация с производителями домофонов ни чем не отличается. Novex SeeBlueR Pre-Stained Standard (Life Technologies) was loaded in the first lane of each gel to estimate the molecular weight (MW) of the milk proteins and account for gel to gel variation. Reduced disulphide bridges were further stabilized using the alkylating reagent IAA. The solubilisation buffer also contained the anionic detergent SDS which disaggregates casein micelles as well as NaCl which influences their physico-chemical stability.

The 20 most intense peaks with charge state ≥ 2 and a minimum signal threshold of 10,000 were fragmented in the linear ion trap using collision-induced dissociation (CID) with a normalized collision energy of 35%, 0.25 activation Q, and activation time of 10 ms.
Conclusions In this study, three protein extraction methods performed on bulk milk samples from Jersey and Holstein-Friesian cows were compared using protein assay, SDS-PAGE, and nLC-MS/MS analyses. All major milk proteins such as caseins were extracted along with less abundant proteins such as whey proteins (β-lactoglobulin, α-lactalbumin, lactotransferrin), as well as minor proteins such as glycoproteins, and enzymes. Nano-Liquid Chromatography (nLC)-Electrospray Ionization (ESI) Tandem MS (MS/MS) Analyses The nLC-ESI-MS/MS analyses were performed in triplicates (coded i1 to i3) thus yielding 270 MS files.
The inset further details such components without revealing much difference across methods. One peptide per standard was selected and Extracted Ion Chromatograms (EICs) were produced and compared across the standard mixture, Jersey bulk milk, and Holstein bulk mik tryptic digests. Apart from the major milk proteins, many immunoglobulins (Igs) were also identified.
