The production process for A7641 does not involve the use of tris. All pH adjustments and chromatography steps are carried out using Acetic acid or Ammonium hydroxide. The material is essentially free of salts before undergoing lyophilization, although there is a possibility of trace amounts of NaCl due to chromatography. The NaCl concentration would be less than 0.01%.

Description générale
Chicken egg albumin is the major protein constituent of egg whites. Chicken egg albumin is a phosphorylated-glycoprotein. From the amino acid sequence, the peptide portion of the molecule consists of 385 residues and has a molecular weight of 42.7 kDa. [1]
Ovalbumin, an egg white protein is produced in the oviduct of hen. It has 3 sites of post synthetic modification and an N-terminal acetyl group.[2] This product is free of S-ovalbumin, a heat stable form of egg albumin formed when eggs are stored.
Application
Albumin from chicken egg white has been used:
- as a component in reaction buffer for in vitro enzymatic assay[3]
- to simulate dangerous protein toxins[4]
- as a component in marker solution[5]
The product is useful as a marker (∼45 kDa) for protein electrophoresis. It has been used to produce an animal model of asthma.
Ovalbumin was used as medium for cell incubation in EliCell assay for the detection of released cytokines from eosinophil.[6]
It was also used in a study testing intestinal macromolecule absorption in fetal pig after infusion of colostrum in utero.[7]

Actions biochimiques/physiologiques
Differential scanning calorimetry indicates that chicken egg albumin denatures at 84 °C.[8] Ovalbumin can be used as a carrier protein to conjugate to synthetic peptides for use as an immunogen.
Ovalbumin is preferred as a nutrient supplement. It can serve as a drug carrier. It possess tumor necrosis releasing factors, that can play a great role in tumor suppression.[2]

Is there any information available regarding whether chicken egg white albumin product A7641 was prepared in a buffer solution containing tris prior to lyophilization, or if it was prepared from a pure form of chicken egg white albumin without any buffer?
