The relationship between lysate protein concentration from untreated and UV-treated 293 cells and the absorbance at 450 nm using PathScan® SAPK/JNK Sandwich ELISA Antibody Pair #7219 is shown. 293 cells were treated with UV, allowed to recover for 30 minutes at 37ºC and then lysed.Learn more about how we get our images
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
1X Cell Lysis Buffer: 10X Cell Lysis Buffer (#9803): To prepare 10 ml of 1X Cell Lysis Buffer, add 1 ml of 10X Cell Lysis Buffer to 9 ml of dH2O, mix. Buffer can be stored at 4°C for short-term use (1–2 weeks).
Recommended: Add 1 mM phenylmethylsulfonyl fluoride (PMSF) (#8553) immediately before use.
STOP Solution: (#7002)
NOTE: Reagents should be made fresh daily.

CST's PathScan® Total SAPK/JNK Sandwich ELISA Antibody Pair is offered as an economical alternative to our PathScan® Total SAPK/JNK Sandwich ELISA Kit #7330. Capture and Detection antibodies (100X stocks) and HRP-conjugated secondary antibody (1000X stock) are supplied. Sufficient reagents are supplied for 4 x 96 well ELISAs. The SAPK/JNK Capture Antibody is coated in PBS overnight in a 96 well microplate. After blocking, cell lysates are added followed by SAPK/JNK Detection Antibody and Anti-Rabbit IgG, HRP-conjugated antibody. HRP substrate, TMB, is added for color development. The magnitude of the absorbance for this developed color is proportional to the quantity of total SAPK/JNK protein.
Antibodies in kit are custom formulations specific to kit.
Antibody pairs have been optimized using recommended buffers, reagents, plates and the included protocol. Solutions should be made fresh daily.
Capture and detection antibodies are stored at 4°C. HRP-linked secondary reagent is stored at -20°C.
For Antibody Pair specificity and sensitivity, please refer to the corresponding PathScan® Sandwich ELISA Kit. Note: This antibody pair detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.
The stress-activated protein kinase/Jun-amino-terminal kinase SAPK/JNK is potently and preferentially activated by a variety of environmental stresses including UV and gamma radiation, ceramides, inflammatory cytokines, and in some instances, growth factors and GPCR agonists (1-6). As with the other MAPKs, the core signaling unit is composed of a MAPKKK, typically MEKK1-MEKK4, or by one of the mixed lineage kinases (MLKs), which phosphorylate and activate MKK4/7. Upon activation, MKKs phosphorylate and activate the SAPK/JNK kinase (2). Stress signals are delivered to this cascade by small GTPases of the Rho family (Rac, Rho, cdc42) (3). Both Rac1 and cdc42 mediate the stimulation of MEKKs and MLKs (3). Alternatively, MKK4/7 can be activated in a GTPase-independent mechanism via stimulation of a germinal center kinase (GCK) family member (4). There are three SAPK/JNK genes each of which undergoes alternative splicing, resulting in numerous isoforms (3). SAPK/JNK, when active as a dimer, can translocate to the nucleus and regulate transcription through its effects on c-Jun, ATF-2, and other transcription factors (3,5).
