With forty-eight slots in a 4 x 12 grid that empties into a single lower chamber, the PR 648 has a fitting for attaching a vacuum pump or aspirator to draw samples through the slot. Proceed with immunodetection (see Immunodetection using a chemiluminescent detection method or Immunodetection using a chromogenic detection method). The Hoefer Scientific PR 648 Slot Blot Blotting Manifold provides a simple, convenient method for screening recombinant clones, DNA, RNA and proteins.Tip: For larger sample volumes, suitable equipment is available from several suppliers. After applying the samples, the membrane should be dried for a short time at room temperature before proceeding with the detection process.

Numbered slots facilitate accurate sample application. Each well holds up to 1 ml sample volume. In the mRNA half-life experiments, aliquots (5 g) of the RNA sample were spotted onto Hybond-N nylon membrane using a HSI-PR 600 slot-blot apparatus (Hoefer. Screens as many as 48 samples quickly and easily. In most cases diluting the protein with buffer containing denaturing reagents will increase epitope exposure and give better results. The HOEFER SLOT BLOT MANIFOLD offers a simple, convenient method for screening recombinant clones, DNA, RNA and proteins. Note: Under native conditions especially, the antibody epitope must be at least partially exposed to allow antibody binding. It is also possible to use crude cell lysate and apply 1 µl samples with an estimated concentration of 1–100 ng/µl protein. Apply 1 µl samples of diluted protein directly onto membrane.Tip: The protein of interest is diluted in dilution buffer for denaturing conditions, dilution buffer for native conditions, or another preferred buffer. Dilute protein samples in buffer to final protein concentrations of 1–100 ng/µl. To ensure a seamless contact between the resolving and stacking gels, remove residual liquid by blotting one corner with a lab wipe.
