Application CommentsProtocol
Note: This protocol is provided only as a guide. Variables associated with the individual assay conditions will dictate the optimal working dilutions.

1. Soak the blot in 100% methanol until the blot is wet, followed by 2 washes with TBST (25 mM Tris-HCl, pH 8.0, 125 mM NaCl, 0.01% Tween®-20 detergent) to remove any residual methanol.
2. Incubate the blot for 1 h with 2% nonfat dry milk in TBST to block non-specific binding.
3. Incubate the blot with primary antibody in 2% milk/TBST for 1-2 h at room temperature or overnight at 4°C. Dilute the primary antibody according to the manufacturer's recommendations.
4. Following incubation with the primary antibody, wash the blot 5 times in TBST and incubate with a secondary antibody conjugated to horseradish peroxidase for 1 h at room temperature. Dilute the secondary antibody according to the manufacturer's recommendations.
5. Wash 5 washes with TBST and develop the blot for ~5 min using a chemiluminescence substrate.
6. Expose the blot to X-ray film for an appropriate time period (usually 10 s to 20 min) to visualize the protein bands.

ApplicationImmunoblotting (see comments)
DescriptionINSTA-Blot™ ready-made blots eliminate the preparation of tissue lysates and the running and transferring of SDS-PAGE gels. The INSTA-Blot™ Human Tissues contains approximately 20 µg per lane of different human tissues, resolved onto Immobilon membrane. The membrane is stained with amido black to permit quantitation of proteins prior to immunoblotting. The blot contains the following tissues:

Lane 1. Molecular weight marker
Lane 2. Brain
Lane 3. Heart
Lane 4. Small Intestine
Lane 5. Kidney
Lane 6. Liver
Lane 7. Lung
Lane 8. Skeletal Muscle
Lane 9. Stomach
Lane 10.Spleen
Lane 11.Ovary
Lane 12.Testis

MW Markers: 180 kDa, 116 kDa, 97 kDa, 66 kDa, 48 kDa, 29 kDa, 18 kDa, and 14 kDa.
BackgroundThe identification of the human genome has promoted novel studies involving aging, behavioral research, diabetes and obesity, immunology, bioassay and pharmacological screening. Immunoblot analysis assists scientists conducting such research to make important contributions to functional genomics, allowing for structural, functional, and comparative analysis of proteins in human models. Calbiochem® brand is pleased to introduce a ready-to-use membrane that provides a simple and fast solution for screening the expression of a particular protein in human tissue.
FormMembrane containing immobilized proteins
Recommended reaction conditionsINSTA-Blot™ Protocol: 1. Soak the blots in 100% methanol until the blot is wet, followed by washing with TBST (25 mM Tris-HCl, pH 8.0, 125 mM NaCl, 0.01% Tween 20®)-detergent twice to remove any residual methanol. 2. Incubate the blots for 1 h with 2% nonfat dry milk in TBST to block non-specific binding. 3. Incubate the blots with primary antibody in 2% milk/TBST for 1-2 h at room temperature or overnight at 4°C. The primary antibody can be either a purified monoclonal antibody or polyclonal antibody at a standard concentration of 1-2 μg/ml or as a hybridoma tissue culture supernatant diluted 1:5 with 2% milk/TBST. 4. After incubation with the primary antibody, wash the blots 5 times in TBST and incubate with a secondary antibody conjugated to horseradish peroxidase (~1:1000-1:3000 dilution) for 60 min at room temperature. 5. After 5 washes with TBST, develop the blots for 5 min usinga chemiluminescence substrate (for example, SuperSignal® HRP Substrate, Cat. No. 69059). 6. Expose the blots to X-ray film for an appropriate time period (usually 10 s to 20 min) to visualize the chemiluminescent signal corresponding to the specific antibody-antigen reaction. Note: This protocol is provided only as a guide. Variables associated with the individual assay conditions will dictate the optimal working dilutions. Colorimetric detection (either alkaline phosphatase or HRP-conjugated secondary antibody and an appropriate substrate) may also be used; however, chemiluminescent detection is more suitable for weakly expressed proteins.
