A human adenocarcinoma of the cervix. HeLa cells have been reported to contain human papilloma virus 18 (HPV-18), low expression of p53, and normal levels of Rb. Useful as a positive control for Western blotting of many different proteins, particularly cytokeratins, proteases, and those proteins involved in the apoptotic process.

Application CommentsSuggested Preparation for Use

Laemmli Sample Buffer (SDS-PAGE)
Resuspend the frozen cell pellet by adding 1.0 ml of Laemmli sample buffer (containing fresh 2-mercaptoethanol, 2-ME, at a final concentration of 500 mM) to the vial containing the cell pellet followed by gentle vortexing. (Alternatively dithiothreitol (DTT) to a final concentration of 100 mM may be substituted for the 2-ME). Heat the sample for 5 min at 90°C. Apply 15-25 µl to each lane of the gel. This is a starting amount, as actual amounts for optimal protein detection need to be experimentally determined for every antibody. Freeze the unused material in 25 µl aliquots and store at -70°C. (Before using the frozen samples, fresh 2-ME or DTT should be added and the sample heated for 5 min at 90°C).

Lane's Sample Buffer (IP/Immunoblot applications)
Resuspend the frozen pellet by adding 1.0 ml of Lane's lysis buffer (150mM NaCl, 50 mM Tris-HCl, pH 8.0, 5 mM EDTA, and 1% NP40) to the vial containing the cell pellet followed by gentle vortexing. Fresh 2-mercaptoethanol, 2-ME, must be added to the vial at a concentration of 500 mM prior to heating the sample for 5 min at 90°C. (Alternatively dithiothreitol (DTT) to a final concentration of 100 mM may be substituted for the 2-ME). Apply 15-25 µl to each lane of the gel. This is a starting amount, as actual amounts for optimal protein detection need to be experimentally determined for every antibody. Freeze the unused material in 25 µl aliquots and store at -70°C. (Before using the frozen samples, fresh 2-ME or DTT should be added and the sample heated for 5 min at 90°C).

Revision25-October-2007 RFH
DescriptionThe Calbiochem® Cell Pellets are a collection of frozen cell pellets representing cell lines most commonly used for internal controls in immunoblotting and IP/immunoblotting applications. Cells are grown under standard conditions to a density of approximately 80-85% confluency, washed extensively to remove excess culture medium derived proteins (predominantly serum albumin) and then pelleted and flash frozen. Pellets are designed to be lysed by the addition of Laemmli sample buffer for SDS-PAGE applications. Alternatively, the pellet may be lysed using alternative buffers such as Lane's Buffer or specific buffers with lower concentrations of detergent for IP/immunoblotting applications. Vial containing 10 X 106 of the indicated cell type, flash frozen at -70°C.
BackgroundHeLa cells are derived from a human adenocarcinoma of the cervix and have been reported to contain human papilloma virus 18 (HPV-18), low expression of p53 and normal levels of Rb. HeLa is commonly used as a source of many different proteins, particularly cytokeratins, proteases, and those proteins involved in the apoptotic process. To preserve phosphorylation, orthovanadate should be included in the lysis buffer.
