Form:

Liquid or Lyophilized powder

Buffer:

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Research Areas:

Others

Function:

Acts as a regulator of the microfilament network governing cellularization of the embryo. Determines the timing of a key conformational transition in the cortical microfilament network

Involvement in disease:

Relevance:

Acts as a regulator of the microfilament network governing cellularization of the embryo. Determines the timing of a key conformational transition in the cortical microfilament network: the proper coordination of membrane invagination and basal closure of the cells. To do this, bnk possibly physically links neighboring contractile units of the early cycle 14 microfilament network in a manner that prevents basal constriction until the proper stage has been reached. Bnk together with nullo and Sry-alpha may provide auxiliary functions, by acting both to stabilize a large and dynamic microfilament structure and regulate its functions.

Reconstitution:

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
