常规说明
Recommended control: Human wild-type A-431 cell line (ab275462).
Cryopreservation cell medium: Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.
Culture medium: McCoY5a + 10% FBS
Initial handling guidelines: Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.
1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method. Based on cell count, seed cells in an appropriate cell culture flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules.
4. Incubate the culture at 37°C incubator with 5% CO2. Cultures should be monitored daily.Subculture guidelines:
- All seeding densities should be based on cell counts gained by established methods.
- A guide seeding density of 2x104 cells/cm2 is recommended.
- A partial media change 24 hours prior to subculture may be helpful to encourage growth, if required.
- Cells should be passaged when they have achieved 80-90% confluence.

相关性
Interleukin 1 receptor antagonist inhibits the activities of interleukin 1 alpha and beta, and modulates a variety of interleukin 1 related immune and inflammatory responses. This gene and five other related cytokine genes form a cluster spanning approximately 400 kb on chromosome 2. A polymorphism of this gene is associated with increased risk of developing osteoporosis and gastric cancer. Four alternatively spliced transcript variants encoding differentt isoforms have been reported.

Western blot - Human IL1RN (IL1 Receptor Antagonist) knockout A-431 cell line (ab273379)All lanes : Anti-IL-1RA antibody [EPR6483] (ab124962) at 1/50000 dilution
Lane 1 : Wild-type A431 cell lysate

Performed under reducing conditions.
Observed band size: 18 kDa why is the actual band size different from the predicted?False colour image of Western blot: Anti-IL-1RA antibody [EPR6483] staining at 1/50000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab124962 was shown to bind specifically to IL-1RA. A band was observed at 18 kDa in wild-type A431 cell lysates with no signal observed at this size in IL1RN knockout cell line ab273379 (knockout cell lysate ab275530). To generate this image, wild-type and IL1RN knockout A431 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Immunocytochemistry - Human IL1RN knockout A-431 cell line (ab273379)IL-1RA staining observed in wild-type A431 cells (top panel) and IL1RN knockout A431 cells (bottom panel). The cells were fixed with 100% methanol (5 min) then permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with an anti-IL-1ra antibody at 10μg/ml concentration (shown in green) and ab195889 (Mouse monoclonal to alpha Tubulin - Alexa Fluor® 594) at 1/250 dilution (shown in red) overnight at 4°C. Nuclear DNA was labelled in blue with DAPI.
Image was taken with a confocal microscope (Leica-Microsystems TCS SP8). -

Observed band size: 18 kDa why is the actual band size different from the predicted?Lanes 1 - 4: Merged signal (red and green). Green - Anti-IL-1ra antibody observed at 18 kDa. Red - loading control ab8245 (Mouse anti-GAPDH antibody [6C5]) observed at 37 kDa.
Anti-IL-1ra antibody was shown to react with IL-1ra in wild-type A431 cells in Western blot with loss of signal observed in IL-1RA knockout cell line ab273379 (IL-1RA knockout cell lysate ab275530). Wild-type A431 and IL-1RA knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in fluorescent western blot (TBS-based) blocking solution before incubation with anti-IL-1ra antibody and ab8245 (Mouse anti-GAPDH antibody [6C5]) overnight at 4°C at 0.5 µg/ml and a 1 in 20000 dilution respectively. Blots were incubated with Donkey anti-Goat IgG H&L (IRDye® 800CW) preabsorbed (ab216775) and Donkey anti-Mouse 680RD secondary antibodies at 1 in 20000 dilution for 1 h at room temperature before imaging.

Sandwich ELISA - Human IL1RN knockout A-431 cell line (ab273379)Human IL-1RA concentration was interpolated from the IL-1RA standard curve. Supernatants from cell culture samples were serially diluted and assessed by the Human IL-1ra ELISA Kit (ab211650). Wild-type A-431, IL1RN knockout A-431 (ab273379) and THP-1 cells were assessed in duplicate (n=2). Data are represented as the mean and error bars represent standard deviation.
