{{/_source.additionalInfo}}Anti-PsbH | Small subunit H of PSII
(Cat#: AS06 157)
Description
- Immunogen: KLH-conjugated synthetic peptide chosen from PsbH protein of Arabidopsis thaliana P56780, AtCg00710
- Host: Rabbit
- Clonality: Polyclonal
- Purity: Serum
- Format: Lyophilized
- Quantity: 100 µl
- Reconstitution: For reconstitution add 100 µl of sterile water
- Storage: Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.

- Confirmed reactivity: Abies balsamea, Arabidopsis thaliana, Hordeum vulgare, Pinus strobus, Spinacia oleracea, Synechococcus sp. PCC 7942
- Not reactive in: No confirmed exceptions from predicted reactivity are currently known
- The PsbH protein was originally named 10- or 9-kDa phosphoprotein in higher plant chloroplasts. It is encoded by the plastome in algae and higher plants. PsbH is also present in cyanobacteria, where it exhibits 56% amino acid identity with the corresponding protein from Arabidopsis. The protein contains 63–90 amino acids, depending on the species, with molecular masses between 7.0 and 9.9 kDa.PsbH is an intrinsic membrane protein with a single transmembrane helix and its N-terminal region has been suggested to be exposed to the stromal side of the thylakoid membrane. Presence of PsbH already present in etiolated tissue can indicate that the protein may be involved in early stages of PSII assembly.Obtained biochemical data from PSII complexes isolated from spinach suggest that PsbH, together with other PSII phosphoproteins, may be required for D1 protein turnover by regulating dimeric and monomeric PSII transition through their phosphorylation and dephosphorylation.

- LMW proteins can sometimes interfere with chlorophyll, but most chlorophyll can be removed by precipitating sample in acetone before loading on a gel.Protocol: Add acetone to final concentration of 80% ice-cold acetone. Leave 10 minutes. Spin. Rresuspend pellet in solubilisation buffer and load on a gel.
