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 seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 60-70% confluent.
5. Once confluent passage into an appropriate 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. Cultures should be monitored daily.
We will provide viable cells that proliferate on revival.

False colour image of Western blot: Anti-TMPRSS2 antibody [EPR3862] staining at 1/2000 dilution shown in green; Mouse anti-GAPDH antibody [6C5] (Anti-GAPDH antibody [6C5] - Loading Control ab8245) loading control staining at 1/20000 dilution shown in red.
In Western blot Anti-TMPRSS2 antibody [EPR3862] ab109131 was shown to bind specifically to TMPRSS2. A band was observed at 55 25 kDa in wild-type LNCaP and at 25 kDa in Caco-2 cell lysates with no signal observed at this size in TMPRSS2 knockout LNCaP cell line ab273745 (knockout LNCaP cell lysate Human TMPRSS2 knockout LNCaP cell lysate ab275499) and TMPRSS2 knockout Caco-2 cell line Human TMPRSS2 knockout Caco-2 cell line ab273737 (knockout Caco-2 cell lysate ab277340).
To generate this image wild-type and TMPRSS2 knockout cell lysates were analysed. First samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 5 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °. 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 (IRDye® 800CW) preabsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) at 1/20000 dilution.

Anti-TMPRSS2 antibody [EPR24407-87] ab280567 staining TMPRSS2 in wild-type LnCAP cells (top panel) and TMPRSS2 knockout LnCAP cells (ab273745) (bottom panel). The cells were fixed with 4% paraformaldehyde (10 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 Anti-TMPRSS2 antibody [EPR24407-87] ab280567 at 1μg/ml concentration and Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291 (Mouse monoclonal to alpha Tubulin) at 1/1000 dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a goat secondary antibody to rabbit IgG (Alexa Fluor® 488) (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed ab150081) at 2 μg/ml (shown in green) and a goat secondary antibody to mouse IgG (Alexa Fluor® 594) (Goat Anti-Mouse IgG H&L (Alexa Fluor® 594) preadsorbed ab150120) at 2 μg/ml (shown in red). Nuclear DNA was labelled in blue with DAPI.
Image was taken with a confocal microscope (Leica-Microsystems TCS SP8).
Human TMPRSS2 concentration was interpolated from the TMPRSS2 standard curve. Supernatants from cell culture samples were serially diluted and assessed by the Human TMPRSS2 ELISA Kit (Human TMPRSS2 ELISA Kit ab283552). Wild-type and TMPRSS2 knockout LNCaP (ab273745) cells were assessed in duplicate (n=2). Data are represented as the mean and error bars represent standard deviation.
79 bp deletion in exon 3
Blocking and diluting buffer and concentration: Intercept® (TBS) Blocking Buffer diluted with an equal volume of TBSLysates at 20 µg per lane.
The samples were run on a Bis-Tris gel under reducing conditions.
Western blot: Anti-TMPRSS2 antibody (Anti-TMPRSS2 antibody [P5H9-A3] ab309546) staining at 1/1000 dilution, shown in green; Rabbit anti-GAPDH antibody (Anti-GAPDH antibody [EPR16891] - Loading Control ab181602) loading control staining at 1/20000 dilution, shown in red.
In Western blot, Anti-TMPRSS2 antibody [P5H9-A3] ab309546 was shown to bind specifically to TMPRSS2. Target of interest was observed at 55 kDa and 25 KDa in wild-type LNCaP cell lysates (lane 1) with no signal observed at this size in TMPRSS2 knockout cell line (lane 2, knockout cell line ab273745). To generate this image, samples were first run on an SDS-PAGE gel then transferred onto an immobilon-FL PVDF membrane. Membranes were blocked in a fluorescent western blot (TBS-based) blocking solution before incubation with primary antibodies overnight at 4 °C. Blots were washed in TBS-T, incubated with secondary antibodies Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution for 1 h at room temperature, washed again then imaged.
The molecular weight observed is consistent with what has been described in the literature (PMID: 35104687).
