SDS denatures the protein by binding to their polypeptide backbone, conferring a negative charge to the polypeptide which is proportional to its length. Laemmli buffer contains the following chemicals and these are their function: Generally, to denature the proteins a loading buffer (Laemmli buffer) containing the anionic denaturing detergent (SDS) is added to the sample. Therefore, in order to allow the Abs to access it, the protein must be unfolded (denatured). This can be useful when trying to obtain a signal from a weakly-expressed protein.Īntibodies usually recognise a small portion of the specific protein and this domain may reside within the 3D conformation of the protein. *Proteins that can be found on sub-cellular location can be enriched in the lysate of the sub-cellular fraction using specific protocols. Most antibodies will recognise proteins in their denatured form, however, it is important to notice that some antibody (it will be specified on the data sheet) will recognise proteins only on their naive form, thus denaturing detergents should be avoided in this case (mild non-ionic detergents such as NP-40 and Triton X-100 can be used if necessary). Most of the lysis buffer contains denaturing and reducing agents such as sodium dodecyl sulphate (SDS) and other ionic detergents. There are a variety of recipes for lysis buffer which differ according to specific proteins and antibodies. This will also solubilise the protein allowing them to migrate individually and separate through a gel by electrophoresis. Lysis can be performed through mechanical (i.e. To prepare a sample for running on a gel, cells and tissues must be lysed to release the protein of interest.
