애플리케이션

Detects glycoproteins containing α-D-mannose, α-D-glucose when used with appropriate peroxidase substrate
General Western Blot Protocol:
  • Glycoprotein sample size: 500ng
  • Lectin Concentration: 0.1ug/ml

  1. Load samples at 500 ng of glycoprotein per lane
  2. Run 4-20% Bis-Tris SDS page gel
  3. Transfer gel to a PVDF membrane
  4. Block membrane for 1 hr at RT with RIPA buffer (R0278 Sigma)
  5. Incubate HRP lectin at 0.1ug/ml with RIPA buffer for 2 hours at RT
  6. Wash membrane 5 x 5 minutes with 25ml RIPA buffer
  7. Detect using chemiluminescent substrate (CPS1-120)

생화학적/생리학적 작용

Con A is not blood group specific but has an affinity for terminal α-D-mannosyl and α-D-glucosyl residues. Ca2+ and Mn2+ ions are required for activity. Con A dissociates into dimers at pH 5.6 or below. Between pH 5.8 and pH 7.0, Con A exists as a tetramer; above pH 7.0 higher aggregates are formed. Con A exhibits mitogenic activity which is dependent on its degree of aggregation. Succinylation results in an active dimeric form which remains a dimer above pH 5.6.

Package size based on protein content

단위 정의

One unit will form 1 mg purpurogallin in 20 sec from pyrogallol at pH 6.0 at 20 °C.

물리적 형태

Lyophilized powder containing tris-citrate buffer salts and trace calcium and manganese

제조 메모

Prepared from peroxidase type VI (P8375), using the method of Wilson and Nakane, which promotes conjugation but prevents the interaction between Con A and peroxidase sugar residues.

분석 메모

Where reported, agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 6.8, containing Ca2+ and Mn2+ of a 1 mg per mL solution. This activity is the lowest concentration to agglutinate a 2% suspension of human erythrocytes after 1 hr incubation at 25 °C.
