Subculture procedure	Resuscitation steps: ① Remove the frozen vial from liquid nitrogen or -80 ℃ refrigerator and place it in PE gloves. Quickly immerse it in a 37 ℃ water bath, shake the vial to accelerate dissolution, and dissolve it completely within 1 minute; ② Add the dissolved cell solution into a centrifuge tube containing 9mL of complete medium on a ultra-clean bench, centrifuge at 1000-1200rpm for 5 minutes, discard the supernatant, and resuspend the cells in 1-2mL of complete medium. ③ Add the cell suspension into a T25 flask containing 5-6mL of complete medium and place the flask in an incubator. Cell passage: ① Use a 5ml pipette to directly aspirate the culture medium and blow the cells; ② Observe under the microscope whether the cells are evenly dispersed. ③ Divide the cell suspension into fresh T25 flasks at a ratio of 1:2, add appropriate complete culture medium, mix the cell suspension evenly, and culture it in the incubator.; ④ Pay attention to changes in the pH value of the culture medium and cell density, change the medium regularly (2-3 times a week), and repeat the passage operation or cryopreservation when the cell density reaches 80% -90%.

BV2 mouse microglia

Adherence, epithelial cell-like

No. 337749

Product format: 2ml frozen vial x 2, or T25 flask x 1

Biosafety level: 1 , handle in ultra-clean table or safety cabinet

Growth Condition:37 ℃,5% CO₂ CM1-1 culture solution

Receiving notice: if any abnormality is found on the day of receipt, please contact the customer service within 24 hours. If it is overdue, it is deemed that the cells are well. For the frozen cells, it shall be stored in the refrigerator at -80 ℃ upon arrival. If they are not used for a long time, they shall be transferred to liquid nitrogen for storage overnight. Recovered cells in T25 culture flask, upon receipt, put the culture flask in the incubator for 4h, and then carry out handling procedure. During recovery, each vial shall be used up once and shall not be retained. After recovery, the cells can be passed on to the next generation and can be used normally. Please operate in strict accordance with this instruction, otherwise the replacement of cells are not be available in case of lose of cell viability.

Growth conditions:37 ℃,5% CO₂,CM1-1 culture solution. CM1-1 culture solution: 90% DMEM-H + 10% FBS. DMEM-H:DMEM high sugar culture solution, containing glutamine and sodium pyruvate.

Recovery steps:
(1)Prepare a new 100mm culture dish containing 12ml of the above culture medium;
remove the frozen vial from liquid nitrogen or refrigerator at -80℃, thaw the vial in 37°C water bath for 1-2 minutes. Transfer the vial to biosafety cabinet for culture as soon as the contents are completely thawed.
(2)Draw the solution with a sterile pipette, drip into a new culture dish, and mix it evenly by shaking clockwise;
(3)Put it into incubator (37℃，5%CO₂）, change the media overnight, and it will grow up in 2-4 days.

Subculture/ cryopreservation:remove old medium, and rinse twice with PBS,add 12ml culture media directly,blow the cells with a pipette until they fall off completely, aspirate and dispense into 3~6 culture dishes;Cryopreservation: The suspended cells were transferred to the centrifuge tube for (110g, 3min) centrifugation，after centrifugationterminate digestion with 3ml of cryopreservation solution （90%FBS+10%DMSO), aspirate and dispense into 3 frozen vials, and cryopreserve at -80 ℃ with a programmed cooling box.

Recovery record: According to the recovery instructions, the results of the cell recovery are reported as follows:

item	quality standard	recovery record
viability	adherence is observed in 18 hours, the cell adherence rate ≥ 80.0% in 70hours	adherence is observed in 18 hours, the cell adherence rate ≥ 80.0% in 66hours
cell morphology	adherent, epithelial cell-like	CM1-1 culture medium, adherent, epithelial cell-like, round
attached figure
conclusion	good viability, and no abnormal cell morphology, qualified
