||Bovine milk may contain two types of beta-casein protein, A2 or A1, which differ by a single-point mutation at amino acid position 82 (P82/H82). Recent studies have shown that milk containing the A1 beta casein protein can contribute to issues including gastrointestinal discomfort after ingestion. There is some evidence of a link between ingestion of A1 beta casein protein and the development of Type 1 diabetes.
PE-1832-20 is A2 beta casein protein that is purified in its native form from bovine A2/A2 milk to >95% purity. The milk is collected from commercial cows certified free of disease and BSE by the manufacture of the milk.
|| BEK-2365-1P, Bovine A2 Beta Casein ELISA Kit (1 plate)
C-1780-100, Chicken antibody to bovine A2 Beta Casein Protein: Affinity purified
||Refer to the product label.
||Bovine A2 beta casein differs from A1 beta casein at amino acid position 82 (P82)
||Affinity-purified from organic, natural bovine A2/A2 milk.
||~33 kDa (SDS-PAGE)
||Purified A2 beta Casein protein can be used as a standard in ELISA or Western Blot applications. Other applications not tested.
||Bovine A2 beta casein protein only binds A2-specific antibody as determined by Western Blotting. Protein runs as a single band (> 95%) with very few minor bands (< 5%) on SDS-PAGE gels.
||Affinity-purified, native protein.
||Liquid. Protein is provided as 50 uL aliquot at 0.4 mg/mL in 10 mM borate buffer, pH 8.5, containing 20% glycerol. Does not contain preservatives. Use sterile methods.
||Protein is shipped on ice packs. Upon receipt, aliquot and store product long-term at -20C. Store working aliquots short-term at 2-8C as undiluted liquid for one week. AVOID MULTIPLE FREEZE THAWS.
||12 months from purchase if stored at -20C.
