Buffers

Resisting pH changes, buffers protect samples when acids or alkali is added. Powder and liquid forms efficiently track proteins during electrophoresis isolation and separation. The salty buffers can also be used to calibrate and standardize pH meters for accurate readings. Blocking substances stop antibody attachment to membrane free sites that would produce an interfering background. In various concentrations to fit any need, the buffers may come in liquids or dehydrated formats.

Blocking buffer, fish gelatin

Supplier: Biotium

Fish gelatin is commonly used in blocking solutions to minimise background noise in immunodetection procedures such as Western Blotting and immunostaining. Fish gelatin can be used to block non-specific binding sites on positively charged nylon or PVDF membranes or for blocking and dilution of antibodies during immunostaining procedures. Unlike BSA or milk, fish gelatin does not contain IgG or serum proteins that could cross-react with mammalian antibodies.

SSC buffer, 20X concentrate, pH 7,0

Supplier: Rockland Immunochemicals

Saline-sodium citrate (SSC) buffer is most commonly used as a buffer for the hybridisation process and washing in experiments where spcies of nucleic or ribonucleic acid are to be matched to complimentary sequences (such as Southern and Nouthern blotting, in situ hybridisation, or DNA microarrays). SSC is used to help control the stringency of hybridisation in these steps.
