The ZOOM™ IPGRunner™ System is the first system to offer oil-free, trouble-free 2D electrophoresis in a mini-gel format. First dimension separation isoelectric focusing (IEF) is complete in less than three hours. The mini-gel design of the system is easy to handle, eliminates mineral oil overlays, and allows processing of up to 12 samples at once for high-throughput usage.
The ZOOM™ IPGRunner™ System consists of three main components:
• The ZOOM™ IPGRunner™ Mini-Cell. (Figure 1) includes a high-voltage electrophoresis core and lid assembly that fits a mini-cell chamber identical to the XCell SureLock™ mini-cell. The mini-cell holds two ZOOM™ IPGRunner™ Cassettes. • The ZOOM™ IPGRunner™ Cassettes (Figure 2) are provided ready to use and self-contained, eliminating oil overlays for convenient sample rehydration and IEF. Each cassette holds up to six ZOOM™ Strips. • The ZOOM™ Strips are 7 cm long and contain a thin layer of polyacrylamide gel that includes a fixed pH gradient. Each ZOOM™ Strip is clearly labeled with a unique identifying number, pH range, and orientation marks (Figure 3). ZOOM™ Strips are supplied attached to a tri-fold card (Figure 4) for easy access and removal.
Quick and Simple Set-up Procedure Figure 5 demonstrates how easy and fast it is to load samples and set up the ZOOM™ IPGRunner™ System for IEF. Once IEF is complete, the ZOOM™ IPGRunner™ Mini-Cell can be used with NuPAGE™ and Novex™ ZOOM™ gels to complete SDS-PAGE analysis in 40 minutes.

자주 묻는 질문(FAQ)
What is the protocol for using ZOOM gels after first-dimension separation on an IPG strip?
1) Trim excess plastic from IPG strip
2) Equilibrate IPG strip for 2 x 15 min in 5 mL of the appropriate buffer (Use NuPAGE sample buffer for NuPAGE ZOOM gels and Tris Glycine ZOOM gels). Equilibration buffer: 1X NuPAGE sample buffer, 50 mM DTT.
3) Place equilibrated IPG strip in large well of ZOOM gel. Seal the strip in place with an agarose (0.5%) overlay.
4) Load molecular weight markers in small well of ZOOM gel.
Variations: To alkylate the proteins after reducing them, prior to separation on ZOOM gels: 1) Incubate IPG strip for 15 min in equilibration buffer 2) Transfer strip to Equilibration Buffer containing 125 mM iodoacetamide and lacking reducing agent. Incubate an additional 15 min. To denature the proteins with urea after IEF: 6 M urea can be added to Equilibration Buffer, if desired.
After the first dimension separation using the ZOOM IPGRunner, I do not see any distinct spots. What could the issue be?
Here are the possible causes and solutions:
- Low protein load. Increase the protein load. Use an accurate and sensitive protein estimation method.
- Improper sample preparation. Increase solubilization reagents. Use at least 8 M urea for solubilization. Add DTT and non-ionic detergents (see manual for details)
- Strip not correctly oriented. Align the strip correctly as described in the manual. Be sure to have the gel side up when loading the strip into the ZOOM IPGRunner Cassette.
- Air bubbles between the strip and 2D gel. Smooth out any air bubbles.
- Insensitive detection method. Use sensitive detection methods such as silver staining or immunoblotting.
I just set up the ZOOM IPGRunner for IEF but don't see any current running through the system. What is the issue?
A possible reason is poor contact between electrodes or incomplete circuit. Make sure that you have added 600 µL deionized water to the Electrode Wicks and the gel is exposed at the anodic and cathodic ends of the cassette. Check the power supply. Be sure to set the Load Check to off to enable the power supply to operate at low current.
What are the power supply requirements for the ZOOM IPGRunner?
The ZOOM IPGRunner System should be used with an external DC power supply designed for electrophoresis applications. This power supply must:
- Be isolated from the ground so that the DC output is floating (safety requirement).
- Be programmable, with a 4-protocol minimum.
- Be able to operate at low current (less than 1 mA) as IEF is performed at very low current
Note: Many power supplies automatically shut off when the current drops below 1 mA. You will need a power supply capable of overriding the low current shut-off feature. The electrical leads of the ZOOM IPGRunner Lid are recessed and may not fit into some power supply units. To allow connection of the ZOOM IPGRunner power leads with certain power supplies, use Invitrogen Power Supply Adapters available separately (Cat. No. ZA10001).
What is the tolerance of the ZOOM IPGRunner Mini-Cell to organic solvents?
The ZOOM IPGRunner Mini-Cell is impervious to alcohol, but not compatible with chlorinated hydrocarbons (e.g., chloroform), aromatic hydrocarbons (e.g., toluene, benzene) or acetone.
Myeloid-related protein-14 is a p38 MAPK substrate in human neutrophils.
Authors:Lominadze G, Rane MJ, Merchant M, Cai J, Ward RA, McLeish KR,
Journal:J Immunol
PubMed ID:15905572
The targets of the p38 MAPK pathway that mediate neutrophil functional responses are largely unknown. To identify p38 MAPK targets, a proteomic approach was applied in which recombinant active p38 MAPK and [(32)P]ATP were added to lysates from unstimulated human neutrophils. Proteins were separated by two-dimensional gel electrophoresis, and phosphoproteins ... More
Epstein-Barr virus protein kinase BGLF4 is a virion tegument protein that dissociates from virions in a phosphorylation-dependent process and phosphorylates the viral immediate-early protein BZLF1.

Epstein-Barr virus (EBV) BGLF4 is a viral protein kinase that is expressed in the lytic phase of infection and is packaged in virions. We report here that BGLF4 is a tegument protein that dissociates from the virion in a phosphorylation-dependent process. We also present evidence that BGLF4 interacts with and ... More

Hypoxia is a common environmental stress that influences signaling pathways and cell function. Previous studies from our laboratory have identified significant differences in cellular responses to sustained or intermittent hypoxia with the latter proving more cytotoxic. We hypothesized that differences in susceptibility of neurons to intermittent (IH) and sustained hypoxia ... More
Hsp27 regulates Akt activation and polymorphonuclear leukocyte apoptosis by scaffolding MK2 to Akt signal complex.
Authors:Wu R, Kausar H, Johnson P, Montoya-Durango DE, Merchant M, Rane MJ,
Journal:J Biol Chem
PubMed ID:17510053
We have shown previously that Akt exists in a signal complex with p38 MAPK, MAPK-activated protein kinase-2 (MK2), and heat shock protein 27 (Hsp27) and MK2 phosphorylates Akt on Ser-473. Additionally, dissociation of Hsp27 from Akt, prior to Akt activation, induced polymorphonuclear leukocyte (PMN) apoptosis. However, the role of Hsp27 ... More
