Western Blotting (WB), Immunohistochemistry (IHC), Immunofluorescence (IF)
特异性
Rabbit Anti-MEK1 (Phospho-Ser221) Polyclonal Antibody detects endogenous levels of MEK1 only when phosphorylated at serine 221.
产品特性
Molecular Weight: Predicted Band Size 43 kDa, Observed Band Size 43 kDa
纯化方法
The antibody is affinity-purified from rabbit antiserum by affinity chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide is removed by chromatogramphy using non-phosphopeptide corresponding to the phosphorylation site.
免疫原
Synthesized phosphopeptide derived from human MEK1 around pSer221 (A-N-SP-F-V)
Western blot: 1:500-1:1,000, IHC: 1:50-1:100, IF: 1:100-1:200
限制
仅限研究用
浓度
1 mg/mL
缓冲液
phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150 mM NaCl, 0.02 % sodium azide, and 50 % glycerol
储存液
Sodium azide
注意事项
WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
注意事项
Briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container's cap because small volumes of antibody will occasionally become entrapped in the seal of the product vial during shipment and storage. Avoid repeated freezing and thawing.
