Z-VAD-FMK

Cat. Num. AAA14581

• Purity: 99.41%
• Synonyms: Z-VAD-FMK; N/A; Z-VAD-FMK, inhibitor

• Purity/Purification: 99.41%
• Form/Format: Solid

• CAS: 187389-52-2
• Solubility: H2O: 1mg/ml ; Ethanol: <1mg/ml; DMSO: 93 mg/mL (198.93mM ; )(<1mg/ml refers to the product slightly soluble or insoluble).
• Animal Model: Mice
• Targets(IC50): Caspase
• Analytical Data: HNMR and HPLC: Consistent with Structure
• In vitro: Z-VAD.FMK was a poor inhibitor of PARP protease activity in cell lysates. Z-VAD.FMK (10 ?M) is a potent inhibitor of Fas-induced apoptosis [1]. CPP32 is activated during camptothecin-induced apoptosis, and Z-VAD-fmk blocks all features of apoptosis. However, Z-VAD-fmk is inactive in a cell-free system reconstituted from nuclei of untreated HL60 cells and cytosol from camptothecin-treated cells [2]. z-VAD-FMK suppressed TUNEL and caspase-3 staining in endothelial cells, decreased caspase-3 activation, reduced BBB permeability, relieved vasospasm, abolished brain edema, and improved neurological outcome [3]
• Animal Research: Mice used in this study were 5- to 6-week-old (20 to 22 g) ICR males. Mice were injected with 30 mg/kg LPS from E. coli serotype O111:B4 through the tail vein. Z-VAD.fmk was dissolved at 2 mg/ml in 1% dimethyl sulfoxide in sterile saline, and administered to mice by the method of Rodriguez et al. A single intravenous injection of Z-VAD.fmk (0.25 mg) was made 15 minutes before LPS injection, followed by three intravenous injections of Z-VAD.fmk (0.1 mg each) per hour. Control mice were injected with the same volume of 1% DMSO in sterile saline [4].

Please use it as soon as possible.
• In Vivo Activity: LPS (30 mg/kg) was administered intravenously to Institute for Cancer Research mice. Z-VAD.fmk was injected before and after the administration of LPS. The injection of Z-VAD.fmk suppressed the caspase-3 activity in lung tissues and significantly decreased the number of terminal dUTP nick-end labeling-positive cells [4]. Treatment with the specific caspase inhibitor Z-VAD-FMK (i.p.) prior to heat-killed group B streptococcus (i.p.) delayed but did not prevent preterm delivery [5]
• In vitro: In vitro Z-VAD.FMK was a poor inhibitor of PARP protease activity in cell lysates. Z-VAD.FMK (10 ?M) is a potent inhibitor of Fas-induced apoptosis [1]. CPP32 is activated during camptothecin-induced apoptosis, and Z-VAD-fmk blocks all features of apoptosis. However, Z-VAD-fmk is inactive in a cell-free system reconstituted from nuclei of untreated HL60 cells and cytosol from camptothecin-treated cells [2]. z-VAD-FMK suppressed TUNEL and caspase-3 staining in endothelial cells, decreased caspase-3 activation, reduced BBB permeability, relieved vasospasm, abolished brain edema, and improved neurological outcome [3].
• Cell Research: Z-VAD-FMK is dissolved in DMSO and stored, and then diluted with appropriate medium before use[3]. PCR productscontaining coding sequences for the dSMN (forward primer: 5'-TAA TAC GAC TCA CTA TAG GG AAG ACG TAC GAC GAGTCG-3'; and reverse primer: 5'-TAA TAC GAC TCA CTA TAG GG GTG GTG CTG GCT TCT TTC-3'; product length, 601bps;bold and italics letters represent T7 promoter sequences) and control Drosophila Presenilin (dPsn) gene (forward primer: 5'-TAA TAC GAC TCA CTA TAG GG TG GCT GCT GTC AAT CTC-3'; and reverse primer: 5'-TAA TAC GAC TCA CTA TAG GGCGA TAG CAA CGC TTC TTG-3'; product length: 543bps) are obtained and gel-purified. Double-stranded RNAs (dsRNA) aregenerated by transcription with Ribomax T7 Transcription kit and digested with Rnase-free DNase. The dsRNA products areethanol precipitated and annealed by incubation at 65°C for 30 min and then slowly allowed to cool at room temperature. Theannealed dsRNA products are analyzed on a 1% agaorse gel to ensure the majority of dsRNA existed as a single band. ThedsRNA (2 ug) and/or plasmid DNAs (2 ug) are introduced into cells by using Cellfectin. Caspase inhibition is achieved by using 50 uM of Z-VAD-FMK in the culture medium[3].
• Targets(IC50): Pan-caspase: None
• Preparation and Storage: Store at 0 to 4°C for short term (days to weeks); For long term storage, store at -20°C (months)
