General description

Lectin from Pisum sativum (pea) is a tetrameric glycoprotein of about 48 kDa. It is isolated from peas. Pisum sativum agglutinin is specific for α-D-glucose and α-D-mannose.

Application

Lectin from Pisum sativum (pea) has been used to determine acrosomal status and viability of spermatozoa and to assess sperm acrosome reaction (AR) patterns

Biochem/physiol Actions

Lectin from Pisum sativum (pea) possess anti-hepatoma effect and mitogenicity to lymphocytes, like concanavalin A (Con A).
PSA is not blood group specific, but has an affinity for terminal α-D-mannosyl residues. PSA is a mitogen similar to concanavalin A.

Preparation Note

Conjugates are prepared from affinity purified lectin.

Analysis Note

Agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 6.8, of a 1 mg/ml solution. This activity is the lowest concentration to agglutinate a 2% suspension of human erythrocytes after 1 hr incubation at 25 °C.

The selection of morphologically normal spermatozoa is critical to obtain high breeding performances in boar breeding farms and artificial insemination (AI) centers. Parameters for the selection of semen mainly include total sperm motility, concentration, and morphology. However, these primary parameters
