H_IL-1β Reporter 293 Cell Line
Description
Cat. No: GM-C26463
Product: H_IL-1β Reporter 293 Cell Line


IL-1β is a key pro-inflammatory cytokine in the IL-1 family, produced by monocytes, macrophages, and dendritic cells in response to inflammation. It plays a vital role in immune responses, inflammation, and diseases like infections, autoimmune disorders, and inflammatory conditions. IL-1β binds to its receptor IL-1R1 to trigger effects such as inflammatory cytokine expression, leukocyte recruitment, and adaptive immunity regulation.

IL-1β binds to IL-1R1 with the help of IL-1RAcP to initiate signaling. This recruits MyD88 and activates downstream molecules like IRAK and TRAF6, triggering the NF-κB and MAPK pathways. The result is the expression of pro-inflammatory genes, amplifying the inflammatory response. IL-1 signaling is regulated by inhibitors like IL-1Ra to prevent excessive damage.

H_IL-1β Reporter 293 Cell Line is a clonal stable cell line constructed using lentiviral technology, endogenously expression of the IL-1R1 and IL-1RAcP gene, along with signal-dependent expression of a luciferase reporter gene. When IL-1β binds to IL-1R1 and IL-1RAcP, it activates downstream signaling pathways, leading to the expression of luciferase. Blockade antibodies can inhibit this signal transmission. The luciferase activity measurement indicates the activation level of the signaling pathway and can thus be used to evaluate the in vitro effects of drugs related to IL-1β.
Data
Response to Human IL-1 beta / IL1B Protein. The H_IL-1β Reporter 293 Cell Line (Cat. GM-C26463) at a concentration of 1.5E4 cells/well (96-well format) was stimulated with serial dilutions of Human IL-1 beta / IL1B Protein (Sino Biological/10139-HNAE) in assay buffer (DMEM + 1% FBS + 1% P.S) for 6 hours. The firefly luciferase activity was measured using the GMOne-Step Luciferase Reporter Gene Assay Kit (Cat. GM-040503). The maximum induction fold was approximately [14.5]. Data are shown by drug mass concentration.
Response to Anti-IL-1β hIgG1 Antibody(Canakinumab). Serial dilutions of Anti-IL-1β hIgG1 Antibody(Canakinumab) (Cat. GM-51764AB) was incubated with 0.034 ng/well of Human IL-1 beta / IL1B Protein (Sino Biological/10139-HNAE) for 1 hour in assay buffer (DMEM + 1% FBS + 1% P.S). After pre-incubation, add the mixture to the H_IL-1β Reporter 293 Cell Line (Cat. GM-C26463) at a density of 1.5E4 cells/well in a 96-well format, and incubate for 6 hours. Firefly luciferase activity is then measured using the GMOne-Step Luciferase Reporter Gene Assay Kit (Cat. GM-040503). The results indicated maximum blocking folds of approximately [6.1]. Data are shown by drug mass concentration.
Response to Anti-IL1R1 hIgG1 Antibody(AMG 108). Serial dilutions of the Anti-IL1R1 hIgG1 Antibody(AMG 108) (Cat. GM-51990AB) was incubated with 1.5E4 cells/well of the H_IL-1β Reporter 293 Cell Line (Cat. GM-C26463) in a 96-well plate for 1 hour in assay buffer (DMEM + 1% FBS + 1% P.S). Subsequently, the Human IL-1 beta / IL1B Protein (Sino Biological/10139-HNAE) at a concentration of 0.034 ng/well was added, and the coculture proceeded for an additional 6 hours. Firefly luciferase activity is then measured using the GMOne-Step Luciferase Reporter Gene Assay Kit (Cat. GM-040503). The results indicated maximum blocking folds of approximately [5.6]. Data are shown by drug mass concentration.
The passage stability of response to Recombinant Human IL-1 beta Protein. The passage 6, 16, and 26 of H_IL-1β Reporter 293 Cell Line (Cat. GM-C26463) at a concentration of 1.5E4 cells/well (96-well format) were stimulated with serial dilutions of Recombinant Human IL-1 beta Protein(Sino Biological/10139-HNAE) in assay buffer (DMEM+1% FBS+1% P.S) for 6 hours. The firefly luciferase activity was measured using the GMOne-Step Luciferase Reporter Gene Assay Kit (Cat. GM-040503). Data are shown by drug mass concentration.

Cell Culture

Cell Recovery

Recovery Medium: DMEM+10% FBS+1% P.S

To insure the highest level of viability, thaw the vial and initiate the culture as soon as possible upon receipt. If upon arrival, continued storage of the frozen culture is necessary, it should be stored in liquid nitrogen vapor phase and not at -70°C. Storage at -70°C will result in loss of viability.

a)       Thaw the vial by gentle agitation in a 37°C water bath. To reduce the possibility of contamination, keep the O-ring and cap out of the water. Thawing should be rapid (approximately 2 - 3 minutes).

b)       Remove the vial from the water bath as soon as the contents are thawed, and decontaminate by dipping in or spraying with 70% ethanol. All of the operations from this point on should be carried out under strict aseptic conditions.

c)       Transfer the vial contents to a centrifuge tube containing 5.0 mL complete culture medium and spin at approximately 176 x g for 5 minutes. Discard supernatant.

d)       Resuspend cell pellet with the recommended recovery medium. And dispense into appropriate culture dishes.

e)       Incubate the culture at 37°C in a suitable incubator. A 5% CO₂ in air atmosphere is recommended if using the medium described on this product sheet.

Cell Freezing

Freezing Medium: 90% FBS+10% DMSO

a)          Centrifuge at 176 x g for 3 minutes to collect cells.

b)         Resuspend the cells in pre-cooled freezing medium and adjust the cell density to 5E6 cells/mL.

c)          Aliquot 1 mL into each vial.

d)         Place the vial in a controlled-rate freezing container and store at -80°C for at least 1 day, then transfer to liquid nitrogen as soon as possible.

Cell passage

Growth medium: DMEM+10% FBS+1% P.S+4 μg/mL Blasticidin

For the first 1 to 2 passages post-resuscitation, use the recovery medium. Once the cells have stabilized, switch to a growth medium.

a)          Subculturing is necessary when the cell density reaches 80%. It is recommended to perform subculturing at a ratio of 1:3 to 1:4 every 2-3 days. Ensure that the density does not exceed 80%, as overcrowding can lead to reduced viability due to compression.

b)         Remove and discard culture medium.

c)          Briefly rinse the cell layer with PBS to remove all traces of serum that contains trypsin inhibitor.

d)         Add 1.0 mL of 0.25% (w/v) Trypsin-EDTA solution to dish and observe cells under an inverted microscope until cell layer is dispersed (usually within 30 to 60 seconds at 37°C).

e)          Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal.

f)          Add 2.0 mL of growth medium to mix well and aspirate cells by gently pipetting.

g)         After centrifugation, resuspend the pellet and add appropriate aliquots of the cell suspension to new culture vessels.

h)         Incubate cultures at 37°C.

Subcultivation Ratio: A subcultivation ratio of 1:3 - 1:4 is recommended

Medium Renewal: Every 2 to 3 days

Notes

a)          Upon initial thawing, a higher number of dead cells is observed, which is a normal phenomenon. Significant improvement is seen after adaptation. Once the cells reach a stable state, the number of dead cells decreases after subculturing and the cell growth rate becomes stable.

b)         Ensure that the cell density does not exceed 80%, as overcrowding may lead to reduced viability due to compression.
