STX1A CRISPR Knockout 293T Cell Line

Overview

This product is a stable CRISPR knockout cell line in which STX1A has been disrupted in the HEK293T (Human (H. sapiens)) background using CRISPR-Cas9 genome editing. It provides an isogenic model for loss-of-function studies of STX1A in kidney tissue context. Cells are supplied frozen (1×10⁶ cells / 1.0 ml, BSL-II) and grow as adherent, epithelial monolayers.

CRISPR Knockout Design

• Target gene: STX1A
• Knockout strategy: CRISPR-Cas9–mediated frameshift-inducing INDEL generation; presence of frameshift-inducing indels, confirmed by sanger sequencing
• Parental cell line: HEK293T — Human (H. sapiens), kidney origin

Gene Background

STX1A is a protein-coding gene. Its encoded protein participates in cellular processes relevant to the biological pathways associated with kidney biology. For detailed gene function, pathway context, and disease associations, refer to the NCBI Gene and UniProt entries for STX1A.

Research Applications

• Validate STX1A knockout by Western blot or qPCR versus the isogenic parental HEK293T line.
• Investigate loss-of-function phenotypes: proliferation, viability, morphology, or pathway activity changes.
• Screen drug candidates targeting pathways regulated by STX1A using this KO as an isogenic control.
• Perform rescue experiments by re-expressing wild-type STX1A in the knockout background.
• Conduct transcriptomic or proteomic profiling comparing KO versus parental HEK293T cells.

Important Notes

• Add selection antibiotic to culture medium only after the first passage post-thaw to allow cells to recover.
• Cell viability upon thaw is warranted for 30 days following shipment when handled per abm guidelines.
• For laboratory research use only. Not intended for diagnostic, therapeutic, or clinical applications.

*Do not heat-inactivate

Thawing

1. Thaw cells quickly in a 37°C water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination.

2. Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions.

3. Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media. Centrifuge cells at 125xg for 5-7 minutes.

4. Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask.

5. Incubate the cells at the recommended conditions.

Subculture

Volumes given below are for a T75 flask; proportionally increase or decrease the volume as required per culture vessel size. Subculture cells once the culture vessel is 80% confluent.

1. Aspirate the culture media, and add 2-3ml of pre-warmed 0.25% Trypsin-EDTA (TM050) to the culture vessel.

2. Observe the cells under a microscope to confirm detachment (typically within 2-10 minutes). Cells that are difficult to detach can be put in 37°C for several minutes to facilitate detachment.

3. Neutralize Trypsin-EDTA by adding an equal volume of the complete growth media into the culture vessel.

4. Transfer the culture suspension into a sterile centrifuge tube, and centrifuge at 125xg for 5 minutes. The actual centrifuge duration and speed may vary depending on the cell type.

5. Aspirate the supernatant, and re-suspend the pellet with pre-warmed fresh complete growth media. Add appropriate aliquots of the cell suspension to new culture vessels, as desired.

6. Incubate the cells at the recommended conditions.
