2. Handling
2.1. Safety warnings and precautions
Warning: For research use only.
Not recommended or intended for diagnosis of disease in humans or animals. Do not use internally or externally in humans or animals.
All chemicals should be considered as potentially hazardous. We therefore recommend that this product is handled only by those persons who have been trained in laboratory techniques and that it is used in accordance with the principles of good laboratory practice. Wear suitable protective clothing, such as laboratory overalls, safety glasses and gloves. Care should be taken to avoid contact with skin or eyes. In the case of contact with skin or eyes, wash immediately with water. See material safetydata sheet(s) and/or safety statement(s) for specific advice.
2.2. Storage
The kit should be stored at
2–8°C.
2.3. Expiry
For expiry details see outer
packaging.

3. Components
Protein mixture 250 μg/vial, 10 vials contains the following proteins:
Thyroglobulin (1), porcine thyroid, 76 μg, molecular weight (M r ) 669000
Ferritin (2), equine spleen, 50 μg, M r 440 000
Catalase (3), bovineliver, 36 μg, M r 232 000
Lactate dehydrogenase (4), bovine heart,48 μg, M r 140 000.
Albumin (5), bovine serum, 40 μg, M r 66 000.
The amount of each protein has been chosen to give bands of equal intensity when stained with Coomassie™ Brilliant Blue following electrophoresis. Intensities may vary when using other staining methods.
4. Other materials required
• Electrophoresis reagents appropriate to the application being run.
• Detection reagents appropriate to the application being run.
• Gel electrophoresis equipment.

5. Critical parameters
• Reconstitute the HMW standard vial in appropriate buffer.
• Not recommended for use in denaturing systems i.e. containing sodium dodecyl sulphate.

6. Description
The High Molecular Weight Calibration Kit is a lyophilized mixture of five highly purified well-characterized proteins for use in molecular weight estimation under non-denaturing conditions.
The molecular mass of the protein under investigation is determined by comparing its electrophoretic mobility with that of proteins contained in the kit.
Ten vials are supplied, each containing a lyophilized mixture of highly purified protein standards of molecular mass range (M r ) 66 000 to669 000.

7. Protocol
7.1. Preparation of calibration kit
Reconstitute the contents of a vial in 100 μl of the electrophoresissample buffer appropriate to the application being run. When reconstituted in this volume, the protein solution will also contain about 25% sucrose. It is therefore not necessary to add sucrose,
glycerol or other density enhancing agents to the sample buffer.
For Coomassie Brilliant Blue detection Load reconstituted standards without further dilution.
For silver stain detection
Dilute the reconstituted proteins by at least 50-fold in the electrophoresis sample buffer appropriate to the application being run.
