Anti calreticulin crt

Manufactured by Cell Signaling Technology
Sourced in United States

Anti-calreticulin (CRT) is a laboratory product used for the detection and analysis of calreticulin, a ubiquitous calcium-binding chaperone protein found in the lumen of the endoplasmic reticulum. It functions as a molecular chaperone, facilitating the folding and assembly of newly synthesized proteins.

4T1 cancer cells (1 × 105) seeded in confocal petri dish were incubated with PM, PM@RM and PM@RM-T7 (at the equivalent mPDA = 200 μg/mL, Met = 60 μg/mL) for 6 h. Afterward, the cells were laser irradiated (808 nm, 1.0 W/cm2, 5 min) or not. The medium was changed to a fresh medium. After another incubation for 24 h, 4T1 cells were washed with PBS (pH 7.4) and incubated with 5% bovine serum albumin for 30 min to block unspecific binding of antibodies. Then, the cells were respectively incubated with anti-calreticulin (CRT) and anti-heat shock protein (HSP70) antibodies (Cell Signaling Technology, Danvers, MA, USA) overnight at 4 °C, followed by incubation with the corresponding secondary antibodies for 2 h at 37 °C in the dark. Finally, the cells were visualized under a CLSM (Zeiss) system. The procedures of immunofluorescence (IF) staining of PD-L1 (Beyotime) were the same as the above.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
